Jul ' Post Date Post Date Likes. Alasdair Anderson. However the principles are the same and I offer the below based on my experience. The first question is why do you interpret the busbar short time RMS fault rating as equivalent to Ik? The stress, heating, etc.

I would therefore expect the busbars to need a short time RMS fault rating as higher than Ik though not necessarily as high as I"k in terms of heating. The fault current at the switchboard is also critical in choosing the correct switchgear.

The circuit breakers should operate well before the short time period of the busbar rating so it is critical to know what current they have to interrupt, which is more likely to be the value of I"k than Ik. I hope this helps, but if anyone has anything to add or disagree with I would be interested to hear. Log in. Powered by Personify Community.
