ECN Forum Forums General Topics of the Trade General Discussion Area Will the real 3/8" NMC Connector please stand up?

One of my pet-peaves involving electrical fittings is the inconsistancy in the names of "Romex" Cable connectors.

3/8" NMC Connectors fit into a 7/8" hole, which is the O.D. for trade-size 1/2" pipe.

But, the rest are named with the trade-size, 3/4" NMC Connector fits in a 3/4" trade-size hole (1-1/8"), etc.

The above pictures, in my humble (hah!) opinion, is the real 3/8" NMC Connector.

What say you?
