Wire and breaker size for old clothes dryer
Someone gave me an old but working Kenmore clothes dryer and I would like to hook it up, since using a clothesline is getting old.
My house has a 4 wire receptacle and the wire size of the red, white and black conductors is #10. I did not measure the ground but it looked a bit smaller, possibly #12. There is no breaker in my panel for this circuit.
I checked the circuit breaker that this dryer was attached to and it was a 30A, double-pole. Can anyone tell me if there is a chart somewhere that would specify if you can use a 30A breaker with #10 wire?
Also the dryer has an old-style 3 conductor pigtail on the back. I figure I need to either buy a 4 wire pigtail or replace my receptacle with a 3-hole receptacle. I haven't opened the back of the dryer yet, but I am wondering if there will be a neutral and ground in there that is strapped together that I would need to separate if I want to use a new four wire pigtail. Does anyone have any suggestions?
Thanks a lot.
