Afternoon all
I hope someone can shed some light on what i think is a problem with hevacomp connect, i am currently working on a large project and at the transformer, we have a fault current of 24kA but 10m upstream we have a fault current of 7.9kA so losing 17kA through 3 no. 185mm2 SWA cables.
I thought this may have simply been an error on this project due to entering something incorrectly but a colleague checked a calc they produced and the same happens, it seems the board downstream will let nothing more than 3kA through.
I have tried changing the protective device and this changes nothing on the fault current which remains at 7.9kA.
Any ideas / help would be greatly appreciated.

Wow, thank you very much Duncan, i was dubious about using the likes of a forum to answer this simply due to never having used 1 before. I am sold, you have been excellent, thank you.
a colleague did say could the device be limiting the current.
Honestly, thank you. I will relay this back and may be back with more questions once i have spoken to colleagues
Happy to have helped.
