I assume that’s true for GFCI breakers but anyone who knows, feel free to chime in.
Why would a breaker require a ground? you’re not plugging an appliance into a breaker… the EGC is supplied via a dedicated conductor or metal conduit.
Afternoon, Kenton. Hope this posts finds you well.
Sorry. I never ran across this condition.
If the question is will a GFCI circuit breaker work if there is no EGC in the branch circuit the answer is yes.
