Connect 30A subpanel to 60A/240V A/C Disconnect?
 
Hello all, I have a question I hope I can get some help on. I recently bought a house and had them pre-wire for a hot tub installing a 60A/240V AC Disconnect at the back. Its wired to (2) 50A breakers in the service panel. OK, now that i'm in the house, I'm broke and all the misses and I can afford right now is a hot tub that only requires a 30A/115V service. It would be nice to set it up where i can provide power to the hot tub and then wire up an outlet and some lighting.

The AC Disconnect is a Ferraz Shawmut DSNP60M and page 12 of this pre-delivery instructions shows what I need to connect to: http://www.solanaspas.com/pdfs/solan...ry_inst_04.pdf
so I know i will need at least a 30A GFCI subpanel.

I realize that it can be run off 15A/115V but i dont have an outlet over here and if i have to do something anyway, I may as well do it right. Thanks in advance for any advice on how I go about doing this!

If they ran a 4 wire cable you can simply change the disco to a small sub panel and pull your 120v circuiy from there

I doesnt matter that its a 240v ? I can just connect up a 120v panel and its fine?

The panel will still be 240v, but the breaker will be 1 pole, thus 120v... You should really hire someone if you have any doubts on your ability on this...

Basically, 240 = 2, 120's


Each leg is 120V to ground and 240 volts between them.

you never addressed 220/221's question/statement about the number of wires run to the disconnect.

it is important to the situation.

Technically it wasn't a question, so........ did they run a 4 wire cable ?
