240V Kiln Outlet to Air Conditioner Outlet
 
1 Attachment(s)
I'm replacing a 240V 50A kiln outlet with a 240V 15A breaker, which will have 1 outlet only for a air conditioner 15A. I want to be sure I've done the wiring correctly.
Here is a diagram-

That is correct assuming the green does not connect to the circuit breaker. :thumbsup:

Thanks
 
Thanks, John! The green comes into the box, attaches to a 1 location of 4 screw bar, which the outlet green also connects to. There is no polarity issues with the two blacks, correct?

On a 240 volt circuit, polarity doesn't make any difference at all. Polarity only matters where the neutral is involved. There's no neutral in your circuit. Your drawing will work just fine.

He may encounter a problem getting 50 amp wire to connect to a 20 amp breaker. I believe most 20 amps will accept 8 awg but not 6 awg. This is of course assuming he used a 60 C column cable for the supply to the kiln.

Good point, I guess you could pigtail it. There's no way you'd get even an 8 into a 20 amp receptacle.

awg to breaker

Thank You, for your help!
I was able to attach the heavy kiln wire into the breaker box connectors at the top. I'm not versed in wire sizes- they were about 1/4 dia. multi-strand copper.
From the breaker, I ran 12/3 out to the outlet, this I did not mention. Looks good?

Perfect. It'll work just fine, and I don't see any code issues.

Rob- I sure appreciate your help. Next time I'll hire it out! A bit too much anxiety and a few too many trips for conduit hardware.

John, Stubbie, Thank You, all!
