How to prep for Outdoor jacuzzi electrical
 
I am redoing some landscape at my home where I will be installing some flagstone. before I set it I was thinking of burying some electrical conduit for a Jacuzzi tub I may get in the future.

would it work to run wire for two seperate 20 amp circuits and a single solid copper for dedicated grounding?

if so would it be possible to run this all in one underground conduit?

You need to decide whitch tub you may go with.
some require up to 60 amp 120/240 volt, while others only require 120 volt.

The power for the tub can not be a cable.

thanks, so I am assume you mean by cable the flexible steel conduit. I was planning on running in the PVC outdoor conduit.

The cable can be with or without steel conduit however with spa and Jazzcui will have specfic code to follow and there will be no bare ground conductor at all and it have to be in PVC conduit.

If I were you I will size it plenty big so you can add the THHN/THWN conductors when you get the spa or jacuzzi.

So therefore the conduit size it will be 3/4 inch that is the smallest I will use but 1 inch can be used as well.

some of them will take a bit of power so plan it ahead for larger conductor if the situation called for.

There is a bit of infomation in NEC Art. 680 that will cover this situation very well. and any local codes will be addtion to it.

Merci.

1) Install an equipotential bonding grid below the finished surface where the tub will be placed, before pouring any slab or setting pavers. Leave a tail stubbed up for connection to the tub's bonding lug(s). Document the installation and have it inspected!!

2) Plan on having a small pedestal nearby to mount your disconnect on. A short wood post, or similar structure, or blank section of a deck railing is a good start.

Install your PVC conduit to that point, and stub up just below where the disconnect box will be. That will save you plenty of time in the long run.

AS for the conduit from the disconnect box to the spa tub itself, I'd leave that for later until you actually have the tub on site, since they vary from model to model ....
