And how do I overcome the issues?</span></p> <p><span style="color:#000000;">Schneider ACB&#39;s must be one of the most commonly used protective devices of this type.&nbsp; </span></p> <p><span style="color:#000000;">I too have the need to produce calculations for scrutiny by a Consultant.</span></p> <p><span style="color:#000000;">When will this issue be resolved?&nbsp; Using a Generic ACB does not satisfy the Consultant, they require the verified calculations using the devices we will be installing.</span></p> <p><span style="color:#000000;">Please advise when a fix will be provided.</span></p> </div><div style="clear:both;"></div>Ask A Question Ihttps://communities.bentley.com/achievements/460ac7df-7ccc-4c42-a204-9e05eef3be09Wed, 22 Dec 2021 05:26:57 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:96c37bda-f30d-4959-b6b5-f1bccbd56cd3Ask a question in a forum.
