Wiring a pool


Hello all,

I am putting in an above ground pool and need some assistance with wiring. My pump is a twist lock. There is no such animal as a GFI twist lock receptical so I will use a 20 amp SQD GFCI breaker. My panel is in my garage about 35 feet from the pool. I planned on running the wire out of the panel through conduit down 15 feet of wall and through the wall to the outside, down the wall 18" deep to a 4x4 post. I plan on using a 2 gang weatherproof box with a 2CKNMD cover. My outlet has to be at least 6 ft from the pool. (Not a big deal) One question that I need to know is, when I ground the pool do I have to put a lug on each leg of the pool or is one lug on one leg sufficient. I asked an electrician and he said that is the town who makes that decision. I asked the town and they said we are not electricians, your electrician should have that answer. I asked 3 other electricians and all 3 told me the same story. "Your town has to make that decision". Each town is different and it also depends on the mood of the inspector. One day it could be ground it to one leg the next day it could be ground it to every other leg around the pool and to the ladder if its metal. Can someone help me get around this matter.

Thank you in advance.
Patiently waiting to swim.

Wiring a pool


I come to find out my pool has no metal parts to it at all. The only parts that are metal are the scres that hold the decor legs and rail together. Does this mean I don't have to ground the pool?

you are going have run the equipontentail bonding wire and connect it to four lega around the pool. All the bonding wires will get connect at the lug on the pump

The other of wiring is to feed the gfi convienent outlet and tthan feed the twist lock for the pool pump.
I ussually put the convienent gfi outlet on the side of the house by pool and feeding it with 12/2 nm and than pipe over to the post which have the time clock and twistlock recep. Remember the convienent outlet has to be no further than 20 feet from edge of pool.

If I read it right he says there is NO metal to bond. What "legs" are you referring to?

If there is absolutely no metal parts at all associated with the pool (other than the motor) then no, there will be no bonding.

BTW - What you are talking about is bonding.
Try and keep the terms "bonding" and "grounding" straight. They are two very different things.

The metal legs that hold up the pool have to be bonded.

On above ground pools there is ussualy a metal frame that keeps the pool shape and holds the liner. This metal frame has legs that contact the earth. This frame has to be bonded.

Obviously, and no one is disputing that fact. The key word in your statement is "usually".

According to the OP there is NO metal. Maybe his is composite or fiberglass. They do exist.
Hopefully he will come back and confirm.

The non-metallic legs get bonded with weed-eater string.

If everything is nonmetal except for the screws than the pool shell does not have to be bonded.

What size pool is this and mfg?
