Adding a sub-panel for a Hot Tub?




Salami and


I need to run 240V to my hot tub.
I'd like to take my 240V from my stove (unused) and run it to a small sub-panel in my crawlspace, then have this feed the hot tub and some lighting around it.
The 240V wire running to my stove will be disconnected and will power the new panel.
From that I should have 2 hots and a neutral (although this is the braided alumminum type).
Can I use this to power the panel (providing 2 hots and neutral) while planting a seperate ground stake to run to the new panel for ground?
The Neutral from the stove cable is braided AL. but is totally isolated from the new panel to the old panel neutral bar.

Inside the new panel I'll have a 240v GFI breaker for the hot tub and
a 110V gfi for the lighting.
Is this OK? Im trying to avoid breaking down walls to run anything to my already packed old panel.

I'm in NC, and I was told I need some type of "panic button" near the tub as well - can this just be attached to a junction box near the tub?
QUIXDRAW:
Yeah I do know how to wire a GFI. Done it many times. But I've seen "professionals" stand around in a stupor when trying to wire a 3-phase.
Folks like you create this dilemma.
Who am I going to trust? The incompetent professionals, the "master electrician" who talks down to others (while shouting in caps), or myself?



Answer
Come off of the line side of the panel to feed a sub panel. From sub panel run a disconnect. From disconnect to hot tub. This is my hubbys way of doing it and hes a commercial electrician I would call a pro in though. Good Luck!!!

Answer
If you are filling it with cold water it will take over night to get to around 100 F ( a nice temp for a hot tub) I don't know what kind of heater Maddi has but it is truly amazing.
