No. The receptacle is part of the circuit rating. You'll have oversized conductors, which is okay, but the breaker must be sized according to the circuit's new rating.zappy said:Is this ok to put a 30amp dryer outlet on a 50amp breaker?

The 4-wire requirement has been around for quite a while, can't remember what year it changed, but it has been at least 12-15 years.electricmanscott said:Existing 4 wire circuit?

charlie b said:I didn't see a clear and complete answer here yet. So let me try. Swap out the 50 amp breaker for a 30 amp breaker AND swap out the 50 amp range receptacle for a 30 amp dryer receptacle. Do both, and you will be OK.

It would be my opinion that changing from a 50 amp circuit to a 30 amp circuit created a new circuit and 4 wire cable would be required.monkey said:It changed in 96. I was wondering the same thing, if it was 3 wire or 4 wire. It is legal to reuse a 3 wire, but I wonder if there is any problem with re using a 3 wire in the OP's situation, as it is not being used for it's original purpose?
I disagree. It's not a new installation. It's at most a re-assignment.don_resqcapt19 said:It would be my opinion that changing from a 50 amp circuit to a 30 amp circuit created a new circuit and 4 wire cable would be required.

As the dog says, "Woof, woof!" (Translation: swap out the 50a breaker for a 30a, and you'll be good to go."
zappy said:just went to give a estimate.That's a good question.If it's a 3 wire are you saying i can't use it? I thought if it's existing i could just using it for a different appliance.
What if, say, when a house was built over 12 years ago, a gas dryer was installed, but a 3-condcutor SE cable was run just in case it was ever desired to replace the gas dryer with an electric one?iwire said:I agree with Don, once you change the breaker and the receptacle it is no longer an existing circuit. But ultimately that would be up to the inspector.
LarryFine said:To me, existing means existing; not existing and used at its maximum ampacity, and it suddenly doesn't qualify because we wish to use it at a lower ampacity now. Esisting means it's there now.
