I'm converting a room from a kitchenette to a bathroom, and am installing a big fancy shower with a steam generator. It requires a 15a/220V outlet. The room, which is located as far away from the breaker as physically possible and still be in the same house, has three normal 3 wire/15a/110 outlets (same breaker, shared with adjacent room), and an outlet for a stove, which seems to be on a 40a/220/4 wire.
The 220 outlet seems to be on the same breaker as the stove located a floor beneath it...I don't know this for sure, but there are no other 220 breakers in the panel, so it seems a fair wager. Naturally I'll be testing it to make sure before making any upgrades.
Given the scenario, I figure I have two options: run a new 220 on its own breaker (bleh), or make that existing 220 work. To do the latter, I believe I'll need to put a 15a breaker in somewhere before the shower plug.
How would you do this job? Are there options I'm not realizing? Am I stuck with new wiring or can I make the existing 220 work? How?
