Chiller MCA & MOCP

[gray roberts]

Would a chiller with a nameplate rating of 920 MCA & 1000 Amp MOCP require the branch circuit conductors to be sized per nameplate MCA rating or would the conductors need to be sized per the 1000 amp MOCP per 240.4C?

You can use the MCA to size the conductors.

Thanks for the info.

Thanks for the info.

I thought so too but 4 electrical inspectors say no.

Sounds like they all need a refresher course. :roll:
