Hot tub wiring questions. Possible Wg?

I've got a used "portable" hottub that I am installing at my house. I have read NEC Article 680, and quite a view posts on this and other forums, so I only have a couple questions left.

The spa controller/heater has GFI on it, and it's a 120/240V controller, with outlets to run the pump and air machines.

First of all, I plan on running the electrical wire (probably THWM, as I understand it) from the breaker box through the wall to outside, and directly under a wood deck. The hot tub will be sitting on a concrete slab on the other side of the deck. Can I run the cable through some type of conduit attached to one of the joists of the deck, or does it need to be buried?

Secondly, do I need to have another disconnect, i.e. on the wall where it exits the house (26ft away from the spa), or is the integrated GFI on the spa controller enough to meet code for maintenance?

Thanks in advance,
Mike

 

Yes the conduit can be run under the deck but is must be secured and it should not pose a tripping hazzard. As for the disconnect I would install one but I'm Just like that. I believe the cord and plug meet the disconnect requirements but I have been wrong b-4.

 

Thanks,

what type of conduit would be the best to attach to the joist, and what kind of disconnect would you use?

PVC pipe is the easiest to use. and will work well for your application. as for the disconnect a simple 2-pole pull out switch is in-expensive and will suit your needs
