They are GFI

Wish i could tell you more but i am not very good w electrical

I do have a exterior breaker under the deck so i have a cut off when servicing or cleaning

All i know is we used big wire if that helps. I replaced electric hot water heater w gas so we used same lines and breaker in box for hot tub

Friend of mine/neighbor is electrician so he did all they work while i watched

We did use same type of cut off as hvac if that helps

What size wire? Rubber flex conduit ok or is the harder, gray, (similar to pvc) glue together stuff better to use. It will be buried in a 18" deep trench. Are these things gfi protected? Can I use a standard 60amp disconnect that is typically used for your outdoor AC unit?

I can safely hook everything up if I had all the correct materials.
Local codes vary. This might help, http://www.spadepot.com/spacyclopedi...FQeR7QodIxgAgg

*#2 wire is what I would use... #4 is OK.
*Rubber flex is OK (liquid-tite) but not the vertical run. Use pipe for that.
* You need a 50-60 amp GFI disconnect for the tub. Square "D" makes a "plastic housed" unit that is very good. Home Depot used to sell them. Cannot be located at the spa/hot tub/unit and that distance is local code. I have 2 one is 15' (FL) the other is 10' (TN) The idea/purpose is for you to "have" to get out of the hot tub to operate the breaker.

I will get my bro-n-law to go pickup the tub manual on Monday and verify if it's a 3 or 4 wire model. Delivery is set for Wednesday. I will do some research to make sure we use large enough wire. Sounds like #6 might not be big enough???
#6 is OK

Looks like a standard double breaker in the house panel, #6 wire (3 conductors) in conduit out to the power box by the tub, that box by the tub will house a 50amp gfi breaker, and a short 4 wire run (red & black hot, white neutral, and green ground) to the tub.

did I miss anything?
Sounds like you are going to install a sub panel, if so local code may require an earth ground at that location.

Also, be sure your wire is suitable for underground use.

Lowes has a hot tub GFI water proof panel for 86 dollars that can be mounted near the tub which should be like 5 feet , #6 wire will work fine , Yes use the gray pipe it's cheap and make sure you run 4 wires to the tub 3 for hook up- 1 ground that goes straight from your home fuse panel to all your motors in your tub

Mine has a 50 amp GFI plus a 60amp pull out switch near the hot tub.

I run 4 wires. Two current and two for ground and neutral. The two G&N are one size smaller.

Do you need to pull a permit for that kind of work? I did when I
put in my H/T. But then again, I went ahead and paid a licensed
electrician so if the house burned down the insurance co. couldn't
deny any claims due to an illegal installation.

Use pvc pipe as conduit. Long sweeps at each box and use a lb for tight corners. Use 1" conduit and the pulling of #6 will ease your pain. I ran 6-4 to mine . 50 amp beaker at pannel and 50 amp spa pack on the wall by the tub.
Remember before inspection all external out lets by the tub need to be covered or removed and blanked off. I think 25ft with the tub but check with inspector. Shore up the bottom of the tub with rubber strips to keep the wood on the bottom from rotten out

I'll be the one to say it. Hire a licensed contractor in the area to (at very least consult) do it. There are national (and possibly local) codes governing the number of conductors, size of the conductors, placement of the disconnect, and requirements for underground circuitry

Doing it improperly (e.g. every post in this thread) will ensure that either it will fail inspection or get someone hurt.

There is a big difference between a dead short in an HVAC system and a dead short with improper grounding/bonding when you are dealing with hot tubs and swimming pools....that difference being death rather than sparks and arcing.
