I am in the process of remodeling my master bath and getting close to the point of doing the electrical. I will be bringing an electrician to do panel work but I am going to run the wires myself.
I have a two panels, seen here.
The thick grey cable coming out of the panel on the right is on a 150A breaker in that panel and goes to a service disconnect in the furnace room. It says not in use and "Old Electric Heat". I would like to add a subpanel in the furnace room to supply power to
the current bath circuit from the main panel will be used for bath lighting and a dedicated 30A for the bath tub.
Questions
- Are there any problems with that?
- Does the service disconnect need to stay and the new subpanel connects to it or does it get replaced with the subpanel?
The main breaker on the panel that feeds that service disconnect is 200A.
By the way, that other thick grey wire coming out on the buttom of the right subpanel is for tennis court lights, which apparently cause sparks (told by the previous owner) and we have not turned them on. I dont really care enough about the tennis at night to bother with it. Just pointing out unused load from that subpanel.
Maybe, but you need to know what the overall house has for a service feed
Since this wire already fed 150a of electric heat I really don;t see any problem putting in a sub. If it worked before pulling up to 150a it should work again
Verify the current wire size to make sure it meets todays code
The only "issue" being if anything was added to that 200a panel in the way of large electric devices after the electric heat was eliminated
The tennis court lights are probably high output - metal halide maybe
If you want lights out there I would replace with CFL floods
I dont need 150 either, it's more like 90, which will actually draw about 75.
I'll check to see what else is on that panel I guess. I know we just eliminated the electric water heater from it and replaced that with a gas tankless, which draws much less.
It looks like you have a "400 amp" service. But yeah, you'll need a 4-wire to your sub panel. The tennis court wire looks like 4-wire and headed that way too, do you know what size it is?

And if its not? Run a new 4 wire to it? If that is the case it maybe better for me to run the 6/2 steam generator and 14/2 GFCI wires to the main panel....
Yes, if you protect the 6-2 with a 50 or 60 A breaker max.
