15 amp 220 washer/dryer hookup
My client is getting a Miele washer and dryer. They're 220v, with the big 4 prong plug, and they say you can use your old 30 amp line to feed them both, and run them both at the same time.
The old dryer was hard wired with 10/3 Bx from the double 30 breaker in a subpanel. I'm installing two big receptacles for the two units, but I have to put in a 4X4 junction box and feed off that.
My question is: can I just use 12/3 Romex to each receptacle, since the appliances are only 15 amps, or do I have to use 10/3? Using Romex is to code here, but the receptacles are capable of handling much more. Since the 12/3 would run separately from the junction box, it should handle the load of 15 amps, right?
I want to do this all to code; a short hank of 10/3 would do it, and I'm prepared to dumpster dive if I have to. But I have the 12/3 on hand.
