Smaller CT than circuit size

1

Hey guys I have some 100 Amp CT’s that I was going to put on a 125 Amp circuit. The circuit isn’t highly utilized but I wanted to make sure that was kosher?

Thanks!

That should be OK. Circuits are supposed to be protected with a breaker that is 125% of expected load. Put another way, the expected load on a circuit should not exceed 80% of the breaker.

Right it won’t exceed 100 amps - maybe ever.
