Dryer Circuit

kornbln

My house was built around 1985 and the dryer circuit is 3-wire. The cable that was used is a black NM cable labeled "10/3" but doesn't say anything about a ground. However, I opened up the dryer receptacle box and I can see paper like the type used to insulate the ground wire in NM cables. Could it be that the ground was snipped at installation since it wasn't required?

By the way, it's a round shaped NM cable like most 3 wire + ground cables are.

Possible make sure you shut breaker OFF when you check.Also might find the wire in the Electrical Panel and trace the ground down (Shut OFF Main )

It would say 10/3 "w/g" (with ground)

I have seen old 10/3 round cable with no ground.

What's the paper for?

To piss off electricians.




It's part of the mfg process.

Hmm, I've only ever seen it wrapped around the bare ground. Why would it be in 10/3 w/o ground?

Because that was the proper way to wire a dryer, with three insulated conductors.

Older wire had paper around everything

I meant why does it have paper without a ground?
