&lt;td&gt;N/A&lt;/td&gt;
&lt;td&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;h1&gt;Overview&lt;/h1&gt;
&lt;p style="text-align:justify;"&gt;The Bentley Hevacomp Connect program comes with a powerful feature to allow the consideration of essential components in a schematic.&lt;/p&gt;
&lt;h1&gt;Method&lt;/h1&gt;
&lt;p style="text-align:justify;"&gt;Consider the following example &amp;ndash; an operating theatre in a hospital will normally be fed from the main supply. Under extreme conditions &amp;ndash; such as a power cut - the main supply could become unavailable and the operating theatre will operate under emergency power supplied by a generator.&amp;nbsp; As it would be unfeasible to run the whole of the theatre from emergency power, only essential services will be available.&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;Any number of supply points can be set up for a Connect projcet. Each supply point has an associated supply cable. Every supply point must be set up to supply a board or busbar in the system. Two or more supply points may both serve the same board or busbar, but only one supply point can be made active at any time and a calculation is carried out with the currently defined supply point. &lt;br /&gt;&lt;br /&gt;In this way you can have say a normal supply and an emergency supply defined (the normal supply not flagged as being essential, the emergency supply flagged as essential) both serving the same main board. You could then make the main supply the normal active supply and calculate the system. If required, you could fix some cable sizes at this stage. &lt;br /&gt;&lt;br /&gt;Then you could make the emergency supply active and recompute the system, this calculation would only consider boards and ways tagged as essential and give results taking into account the previously fixed cables.&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;&amp;nbsp;(The main supply and the generator can be switched between using the &amp;ldquo;Make this active supply for this project&amp;rdquo; option on the Supply data form.)&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;When adding busbars or boards to your schematic, you are given the option of tagging these as being essential or leaving them as non-essential. If tagged as essential you will get the further option of tagging outgoing ways as being essential. If the board or busbar is left untagged then all outgoing ways are considered to be non-essential.&lt;br /&gt;&lt;br /&gt;Take care when designating boards as essential/non-essential through the system. If a board is tagged as essential, but is supplied by a board which is tagged as non-essential, then for an essential supply, the board will not be added into the system.&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;For the sake of simplicity, this layout has all the essential components on the left side. Note that this needn&amp;rsquo;t be the case.&amp;nbsp; Final circuits can be mixed as essential/non-essential on any board as required. The Main Supply, along with Way 2 on the Main Brd and the whole of THRSRV are left as non-essential. Generator Supply, Way 1 on Main Brd and the whole of EMRG are tagged as essential.&lt;/p&gt;
&lt;p&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-18/8713.Essential1.jpg"&gt;&lt;img style="margin-right:auto;margin-left:auto;display:block;" alt=" " src="/resized-image/__size/940x0/__key/communityserver-wikis-components-files/00-00-00-00-18/8713.Essential1.jpg" /&gt;&lt;/a&gt;&lt;/p&gt;
&lt;p style="text-align:center;"&gt;&lt;span style="color:#1e90ff;"&gt;&lt;span style="background-color:#ffffff;"&gt;If a system is calculated using a supply point that is non-essential &lt;/span&gt;&lt;/span&gt;&lt;br /&gt;&lt;span style="color:#1e90ff;"&gt;&lt;span style="background-color:#ffffff;"&gt;then the WHOLE schematic will be calculated&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="text-align:center;"&gt;&lt;span style="color:#1e90ff;"&gt;&lt;span style="background-color:#ffffff;"&gt;If a system is calculated using a supply point that is essential,&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;&lt;span style="color:#1e90ff;"&gt;&lt;span style="background-color:#ffffff;"&gt;then only boards and ways that are also essential will be calculated&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-18/1778.Essential-2.jpg"&gt;&lt;img style="margin-right:auto;margin-left:auto;display:block;" alt=" " src="/resized-image/__size/940x0/__key/communityserver-wikis-components-files/00-00-00-00-18/1778.Essential-2.jpg" /&gt;&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-18/essential-2.jpg"&gt;&lt;/a&gt;When the Main Supply is selected as the active supply for the project, you can see that all components, whether essential or non-essential are included in the calculation.&lt;/p&gt;
&lt;p&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-18/7217.Essential-3.jpg"&gt;&lt;img style="margin-right:auto;margin-left:auto;display:block;" alt=" " src="/resized-image/__size/940x0/__key/communityserver-wikis-components-files/00-00-00-00-18/7217.Essential-3.jpg" /&gt;&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;When the Generator Supply is selected, as this is marked as essential, only the components that are also marked as essential are included.&amp;nbsp;&lt;/p&gt;

&lt;td&gt;N/A&lt;/td&gt;
&lt;td&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;h1&gt;Overview&lt;/h1&gt;
&lt;p style="text-align:justify;"&gt;The Bentley Hevacomp Connect program comes with a powerful feature to allow the consideration of essential components in a schematic.&lt;/p&gt;
&lt;h1&gt;Method&lt;/h1&gt;
&lt;p style="text-align:justify;"&gt;Consider the following example &amp;ndash; an operating theatre in a hospital will normally be fed from the main supply. Under extreme conditions &amp;ndash; such as a power cut - the main supply could become unavailable and the operating theatre will operate under emergency power supplied by a generator.&amp;nbsp; As it would be unfeasible to run the whole of the theatre from emergency power, only essential services will be available.&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;Any number of supply points can be set up for a Connect projcet. Each supply point has an associated supply cable. Every supply point must be set up to supply a board or busbar in the system. Two or more supply points may both serve the same board or busbar, but only one supply point can be made active at any time and a calculation is carried out with the currently defined supply point. &lt;br /&gt;&lt;br /&gt;In this way you can have say a normal supply and an emergency supply defined (the normal supply not flagged as being essential, the emergency supply flagged as essential) both serving the same main board. You could then make the main supply the normal active supply and calculate the system. If required, you could fix some cable sizes at this stage. &lt;br /&gt;&lt;br /&gt;Then you could make the emergency supply active and recompute the system, this calculation would only consider boards and ways tagged as essential and give results taking into account the previously fixed cables.&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;&amp;nbsp;(The main supply and the generator can be switched between using the &amp;ldquo;Make this active supply for this project&amp;rdquo; option on the Supply data form.)&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;When adding busbars or boards to your schematic, you are given the option of tagging these as being essential or leaving them as non-essential. If tagged as essential you will get the further option of tagging outgoing ways as being essential. If the board or busbar is left untagged then all outgoing ways are considered to be non-essential.&lt;br /&gt;&lt;br /&gt;Take care when designating boards as essential/non-essential through the system. If a board is tagged as essential, but is supplied by a board which is tagged as non-essential, then for an essential supply, the board will not be added into the system.&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;For the sake of simplicity, this layout has all the essential components on the left side. Note that this needn&amp;rsquo;t be the case.&amp;nbsp; Final circuits can be mixed as essential/non-essential on any board as required. The Main Supply, along with Way 2 on the Main Brd and the whole of THRSRV are left as non-essential. Generator Supply, Way 1 on Main Brd and the whole of EMRG are tagged as essential.&lt;/p&gt;

&lt;hr style="width:100%;" /&gt;
&lt;p style="text-align:center;"&gt;&lt;span style="color:#800000;background-color:#ffffff;"&gt;If a system is calculated using a supply point that is non-essential &lt;/span&gt;&lt;br /&gt;&lt;span style="color:#800000;background-color:#ffffff;"&gt;then the WHOLE schematic will be calculated&lt;/span&gt;&lt;/p&gt;
&lt;p style="text-align:center;"&gt;&lt;span style="color:#800000;background-color:#ffffff;"&gt;If a system is calculated using a supply point that is essential,&lt;/span&gt;&lt;br /&gt;&lt;span style="color:#800000;background-color:#ffffff;"&gt;then only boards and ways that are also essential will be calculated&lt;/span&gt;&lt;/p&gt;

&lt;td&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;h1&gt;Overview&lt;/h1&gt;
&lt;p style="text-align:justify;"&gt;The Bentley Hevacomp Connect program comes with a powerful feature to allow the consideration of essential components in a schematic.&lt;/p&gt;
&lt;h1&gt;Method&lt;/h1&gt;
&lt;p style="text-align:justify;"&gt;Consider the following example &amp;ndash; an operating theatre in a hospital will normally be fed from the main supply. Under extreme conditions &amp;ndash; such as a power cut - the main supply could become unavailable and the operating theatre will operate under emergency power supplied by a generator.&amp;nbsp; As it would be unfeasible to run the whole of the theatre from emergency power, only essential services will be available.&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;Any number of supply points can be set up for a Connect projcet. Each supply point has an associated supply cable. Every supply point must be set up to supply a board or busbar in the system. Two or more supply points may both serve the same board or busbar, but only one supply point can be made active at any time and a calculation is carried out with the currently defined supply point. &lt;br /&gt;&lt;br /&gt;In this way you can have say a normal supply and an emergency supply defined (the normal supply not flagged as being essential, the emergency supply flagged as essential) both serving the same main board. You could then make the main supply the normal active supply and calculate the system. If required, you could fix some cable sizes at this stage. &lt;br /&gt;&lt;br /&gt;Then you could make the emergency supply active and recompute the system, this calculation would only consider boards and ways tagged as essential and give results taking into account the previously fixed cables.&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;&amp;nbsp;(The main supply and the generator can be switched between using the &amp;ldquo;Make this active supply for this project&amp;rdquo; option on the Supply data form.)&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;When adding busbars or boards to your schematic, you are given the option of tagging these as being essential or leaving them as non-essential. If tagged as essential you will get the further option of tagging outgoing ways as being essential. If the board or busbar is left untagged then all outgoing ways are considered to be non-essential.&lt;br /&gt;&lt;br /&gt;Take care when designating boards as essential/non-essential through the system. If a board is tagged as essential, but is supplied by a board which is tagged as non-essential, then for an essential supply, the board will not be added into the system.&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;For the sake of simplicity, this layout has all the essential components on the left side. Note that this needn&amp;rsquo;t be the case.&amp;nbsp; Final circuits can be mixed as essential/non-essential on any board as required. The Main Supply, along with Way 2 on the Main Brd and the whole of THRSRV are left as non-essential. Generator Supply, Way 1 on Main Brd and the whole of EMRG are tagged as essential.&lt;/p&gt;
&lt;p&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-18/Essential1.jpg"&gt;&lt;img style="margin-right:auto;margin-left:auto;display:block;" alt=" " src="/resized-image/__size/940x0/__key/communityserver-wikis-components-files/00-00-00-00-18/Essential1.jpg" /&gt;&lt;/a&gt;&lt;/p&gt;
&lt;hr style="width:100%;" /&gt;
&lt;p style="text-align:center;"&gt;&lt;span style="color:#800000;background-color:#ffffff;"&gt;If a system is calculated using a supply point that is non-essential &lt;/span&gt;&lt;br /&gt;&lt;span style="color:#800000;background-color:#ffffff;"&gt;then the WHOLE schematic will be calculated&lt;/span&gt;&lt;/p&gt;
&lt;p style="text-align:center;"&gt;&lt;span style="color:#800000;background-color:#ffffff;"&gt;If a system is calculated using a supply point that is essential,&lt;/span&gt;&lt;br /&gt;&lt;span style="color:#800000;background-color:#ffffff;"&gt;then only boards and ways that are also essential will be calculated&lt;/span&gt;&lt;/p&gt;
&lt;hr style="width:100%;" /&gt;
&lt;p&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-18/essential-2.jpg"&gt;&lt;img style="margin-right:auto;margin-left:auto;display:block;" alt=" " src="/resized-image/__size/940x0/__key/communityserver-wikis-components-files/00-00-00-00-18/essential-2.jpg" /&gt;&lt;/a&gt;When the Main Supply is selected as the active supply for the project, you can see that all components, whether essential or non-essential are included in the calculation.&lt;/p&gt;
&lt;p&gt;&lt;img style="margin-right:auto;margin-left:auto;display:block;" alt=" " src="/resized-image/__size/940x0/__key/communityserver-wikis-components-files/00-00-00-00-18/Essential-3.jpg" /&gt;&lt;/p&gt;
&lt;p&gt;When the Generator Supply is selected, as this is marked as essential, only the components that are also marked as essential are included.&amp;nbsp;&lt;/p&gt;

&lt;h1&gt;Overview&lt;/h1&gt;
&lt;p style="text-align:justify;"&gt;The Bentley Hevacomp Connect program comes with a powerful feature to allow the consideration of essential components in a schematic.&lt;/p&gt;
&lt;h1&gt;Method&lt;/h1&gt;
&lt;p style="text-align:justify;"&gt;Consider the following example &amp;ndash; an operating theatre in a hospital will normally be fed from the main supply. Under extreme conditions &amp;ndash; such as a power cut - the main supply could become unavailable and the operating theatre will operate under emergency power supplied by a generator.&amp;nbsp; As it would be unfeasible to run the whole of the theatre from emergency power, only essential services will be available.&lt;/p&gt;

Every supply point must be set up to supply a board or busbar in the system. Two or more supply points may both serve the same board or busbar, but only one supply point can be made active at any time and a calculation is carried out with the currently defined supply point. &lt;br /&gt;&lt;br /&gt;In this way you can have say a normal supply and an emergency supply defined (the normal supply not flagged as being essential, the emergency supply flagged as essential) both serving the same main board. You could then make the main supply the normal active supply and calculate the system. If required, you could fix some cable sizes at this stage. &lt;br /&gt;&lt;br /&gt;Then you could make the emergency supply active and recompute the system, this calculation would only consider boards and ways tagged as essential and give results taking into account the previously fixed cables.&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;&amp;nbsp;(The main supply and the generator can be switched between using the &amp;ldquo;Make this active supply for this project&amp;rdquo; option on the Supply data form.)&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;When adding busbars or boards to your schematic, you are given the option of tagging these as being essential or leaving them as non-essential. If tagged as essential you will get the further option of tagging outgoing ways as being essential.

If a board is tagged as essential, but is supplied by a board which is tagged as non-essential, then for an essential supply, the board will not be added into the system.&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;For the sake of simplicity, this layout has all the essential components on the left side.

The Main Supply, along with Way 2 on the Main Brd and the whole of THRSRV are left as non-essential. Generator Supply, Way 1 on Main Brd and the whole of EMRG are tagged as essential.&lt;/p&gt;

&lt;p style="text-align:center;"&gt;&lt;span style="color:#800000;background-color:#ffffff;"&gt;If a system is calculated using a supply point that is non-essential &lt;/span&gt;&lt;br /&gt;&lt;span style="color:#800000;background-color:#ffffff;"&gt;then the WHOLE schematic will be calculated&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h1&gt;Overview&lt;/h1&gt;
&lt;p style="text-align:justify;"&gt;The Bentley Hevacomp Connect program comes with a powerful feature to allow the consideration of essential components in a schematic.&lt;/p&gt;
&lt;h1&gt;Method&lt;/h1&gt;
&lt;p style="text-align:justify;"&gt;Consider the following example &amp;ndash; an operating theatre in a hospital will normally be fed from the main supply. Under extreme conditions &amp;ndash; such as a power cut - the main supply could become unavailable and the operating theatre will operate under emergency power supplied by a generator.&amp;nbsp; As it would be unfeasible to run the whole of the theatre from emergency power, only essential services will be available.&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;Any number of supply points can be set up for a Connect projcet. Each supply point has an associated supply cable. Every supply point must be set up to supply a board or busbar in the system. Two or more supply points may both serve the same board or busbar, but only one supply point can be made active at any time and a calculation is carried out with the currently defined supply point. &lt;br /&gt;&lt;br /&gt;In this way you can have say a normal supply and an emergency supply defined (the normal supply not flagged as being essential, the emergency supply flagged as essential) both serving the same main board. You could then make the main supply the normal active supply and calculate the system. If required, you could fix some cable sizes at this stage. &lt;br /&gt;&lt;br /&gt;Then you could make the emergency supply active and recompute the system, this calculation would only consider boards and ways tagged as essential and give results taking into account the previously fixed cables.&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;&amp;nbsp;(The main supply and the generator can be switched between using the &amp;ldquo;Make this active supply for this project&amp;rdquo; option on the Supply data form.)&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;When adding busbars or boards to your schematic, you are given the option of tagging these as being essential or leaving them as non-essential. If tagged as essential you will get the further option of tagging outgoing ways as being essential. If the board or busbar is left untagged then all outgoing ways are considered to be non-essential.&lt;br /&gt;&lt;br /&gt;Take care when designating boards as essential/non-essential through the system. If a board is tagged as essential, but is supplied by a board which is tagged as non-essential, then for an essential supply, the board will not be added into the system.&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;For the sake of simplicity, this layout has all the essential components on the left side.

The Main Supply, along with Way 2 on the Main Brd and the whole of THRSRV are left as non-essential. Generator Supply, Way 1 on Main Brd and the whole of EMRG are tagged as essential.&lt;/p&gt;

&lt;p style="text-align:center;"&gt;&lt;span style="color:#800000;background-color:#ffffff;"&gt;If a system is calculated using a supply point that is non-essential &lt;/span&gt;&lt;br /&gt;&lt;span style="color:#800000;background-color:#ffffff;"&gt;then the WHOLE schematic will be calculated&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h1&gt;Overview&lt;/h1&gt;
&lt;p style="text-align:justify;"&gt;The Bentley Hevacomp Connect program comes with a powerful feature to allow the consideration of essential components in a schematic.&lt;/p&gt;
&lt;h1&gt;Method&lt;/h1&gt;
&lt;p style="text-align:justify;"&gt;&lt;span style="font-size:small;"&gt;Consider the following example &amp;ndash; an operating theatre in a hospital will normally be fed from the main supply. Under extreme conditions &amp;ndash; such as a power cut - the main supply could become unavailable and the operating theatre will operate under emergency power supplied by a generator.&amp;nbsp; As it would be unfeasible to run the whole of the theatre from emergency power, only essential services will be available.&lt;/span&gt;&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;&lt;span style="font-size:small;"&gt;Any number of supply points can be set up for a Connect projcet. Each supply point has an associated supply cable. Every supply point must be set up to supply a board or busbar in the system. Two or more supply points may both serve the same board or busbar, but only one supply point can be made active at any time and a calculation is carried out with the currently defined supply point. &lt;br /&gt;&lt;/span&gt;&lt;span style="font-size:small;"&gt;&lt;br /&gt;In this way you can have say a normal supply and an emergency supply defined (the normal supply not flagged as being essential, the emergency supply flagged as essential) both serving the same main board. You could then make the main supply the normal active supply and calculate the system. If required, you could fix some cable sizes at this stage. &lt;br /&gt;&lt;br /&gt;&lt;/span&gt;&lt;span style="font-size:small;"&gt;Then you could make the emergency supply active and recompute the system, this calculation would only consider boards and ways tagged as essential and give results taking into account the previously fixed cables.&lt;/span&gt;&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;&lt;span style="font-size:small;"&gt;&amp;nbsp;(The main supply and the generator can be switched between using the &amp;ldquo;Make this active supply for this project&amp;rdquo; option on the Supply data form.)&lt;/span&gt;&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;&lt;span style="font-size:small;"&gt;When adding busbars or boards to your schematic, you are given the option of tagging these as being essential or leaving them as non-essential. If tagged as essential you will get the further option of tagging outgoing ways as being essential. If the board or busbar is left untagged then all outgoing ways are considered to be non-essential.&lt;br /&gt;&lt;br /&gt;Take care when designating boards as essential/non-essential through the system. If a board is tagged as essential, but is supplied by a board which is tagged as non-essential, then for an essential supply, the board will not be added into the system.&lt;/span&gt;&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;&lt;/p&gt;
&lt;p style="text-align:justify;"&gt;&lt;span style="font-size:small;"&gt;For the sake of simplicity, this layout has all the essential components on the left side. Note that this needn&amp;rsquo;t be the case.&amp;nbsp; Final circuits can be mixed as essential/non-essential on any board as required. &lt;/span&gt;&lt;span style="font-size:small;"&gt;The Main Supply, along with Way 2 on the Main Brd and the whole of THRSRV are left as non-essential. &lt;/span&gt;&lt;span style="font-size:small;"&gt;Generator Supply, Way 1 on Main Brd and the whole of EMRG are tagged as essential.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-18/Essential1.jpg"&gt;&lt;img style="margin-right:auto;margin-left:auto;display:block;" alt=" " src="/resized-image/__size/940x0/__key/communityserver-wikis-components-files/00-00-00-00-18/Essential1.jpg" /&gt;&lt;/a&gt;&lt;/p&gt;

&lt;p style="text-align:center;"&gt;&lt;span style="font-size:small;"&gt;If a system is calculated using a supply point that is non-essential then the WHOLE schematic will be calculated&lt;/span&gt;&lt;/p&gt;
&lt;p style="text-align:center;"&gt;&lt;span style="font-size:small;"&gt;If a system is calculated using a supply point that is essential, then only boards and ways that are also essential will be calculated&lt;/span&gt;&lt;/p&gt;
