Breaker ratings?
Breaker ratings?
(OP)
I've seen more than one client's standard requiring 22kAIC breakers on all 208Y/120V systems. 10k breakers are unacceptable. When asked why - I've always heard "That's the way we've always done it," or "It's our standard." Is there a good reason (or any reason) for this requirement?
Thanks
Thanks
