Wire GFCI location for Hot-tub?

Kinetic · Apr 23, 2023

Hello and thank you for your time.
In the picture, the 6/3 gauge NMD wire is running though the basement ceiling and out of the house into the backyard. Its about 13 in off the ground and about 20 in away from the water line. I have some extra wire slack temporary taped up and covered with a bag.
My question is, when the GFCI box goes over it, can it go overtop at that location (13in off the ground), or will the wire have to elbow joint upwards and run into the GFCI box at some specific height and then of course another line run down again into the ground to the hotub?

I've seen similar wiring set-ups for AC wiring outside the house: wire exits at the same location 13in above ground, then redirect upwards in an cable cover, then into the box and then out again. See image

Sorry for the late reply but it seems to me that you need to install a 50 amp GFCI double pole breaker in the panel. Similar to your HVAC, Lowes sells water proof disconnects made especially for hot tubs. Terminate the wiring in your disconnect and then the hot tub. Good luck

hey, thanks for this, but do I need to raise the GFCI breaker panel up higher than where then wire is exiting out now? Right now its a Romex 6/3 wire coming out of the house. Should it be covered in a conduit of some kind and elbowed up into the GFCI box? Similar to the AC set up.?

If your cable is marked NMD, meaning the insulation spec. is Non Metallic, Dry, then I don't think it is within code to use it outdoors, even if it is put in conduit. Need someone au fait with your regulations (I'm in UK) to confirm, also regarding the use of conduit.

Yes it needs to be sleeved in conduit. Since it’s coming out of the wall install your disconnect so the cable will come in the back of your disconnect

thanks, If the disconnect is 1 foot off the ground, (where the wire is now), will that be ok?
