But the thread size is 1/2" trade (fits into a 7/8" diameter KO just like 1/2" GRC does...)
Nothing on it measures 3/8 of an inch!
It uses 1/2" Locknuts... the same ones that fit on a 1/2" GRC...
GE has one size smaller KO in their residential panels than a 1/2" trade size will fit... This would seem to me to be 3/8" trade size, but it's too small for 3/8" connectors!
What gives?
