New subpanel from old 220 circuit?
Hello: you all helped wonderfully on my last project, now on to the next one! The 13 x 18 ft basement utility room is currently run on one 20A circuit: lights, outlets, toilet pump, and furnace (this county apparently had no codes then, or the builder ignored them). Only have blown the breaker once, and that during a remodel when we moved the kitchen down there.
I plan on finishing the room (man cave....?) and know I need at least two more circuits -- one for the furnace and one for outlets. It is currently concrete on two walls, which I will stub out and drywall.
In that utility room is a 220 outlet the original owner/builder used for a welder. It is on a 50A breaker in the main outside box. It is fed by a three-wire cable that appears to be 6 gauge.
Could I get rid of the 220 outlet and feed a subpanel with this circuit and run a 20A to the furnace and another to some outlets?
