Happy Monday all,

For the installation of a permanently installed "above" ground pool, is equipotential bonding of the perimeter surface required?


Someone called for a quick estimate and I need to get some rough thoughts in my head when looking at the job (residential,single family).

In referencing 680.22, I'm thinking a single twist lock GFCI receptacle for a pool pump located 6' to 10' from the inside wall edge. And a GFCI convenience receptacle located 6' to 20' from the inside wall edge.


I also note 680.21, that "inside" the structure can be "regular" wiring methods....type nm for the pump, but I'm then assuming that "outside" would have to be in a conduit with an insulated grounding conductor.

Questioning the perimeter surface bond, but I'm also assuming bonding would be just from the motor to the metal framing of the pool.

I have to check, I'm not sure of the particulars if there will be a deck around the pool, but if not, how are the ladders (A frame removable) to get in and out of the pool addressed?


Thank you for your insight,
Rich

So the pool will have a deck around it. I will presume a perimeter surface bond is still required.

Turns out, the owner will also be installing a hot tub "on" and existing wood deck.

This deck is on the way from the panel to the pool.

I could run in the house with nmb (1-120v circ pool pump, 1-240v circ hydromassage) then change to conduit outside with an insulated ground for both the tub and pool.
If I choose to run exterior instead below grade, are there any problems with having both the pool and hydromassage circuits in the same conduit......and can they both share the same insulated ground?

The tub will be on a wood deck........I see no need for perimeter surface bond there....although I may also see no need for a perimeter surface bond around the pool since it will have a deck going around it.

Please confirm.......the #8 bond only needs to bond pool metal and equipment and does "not" have to run back to the main panel.



We had a light winter here.....mainly cause I changed my heating system, got a new winter coat, and new snow tires for the truck this year.
This guy jinxed it by talking about swimming pools now it's 30 degrees again.

Alright...........guess I'm on the right track here..........many views with no response so I'll take that as a green light.

Next time maybe I should label the post........ NEEDED: Older person to wire porno pool and hot tub.


:D....ha ha ha

Curious as to where you will find a GFCI twist-lok :D

Note that 680.26 requires bonding of specific parts such as motors, metal fittings , etc. and it is for "bonding" so there is no need to run back to the panel.

There are various opinions on how to handle wood decks.
Here is one thread where it's discussed:

I did and I installed it in the ground below the deck and across the underside of the deck boards -- this was for a hot tub. I think it is silly but....

Dennis........how did you secure to underdecking? RX staples? Brass lugs with brass screws? Just wondering.....thanks

IMO, you need epb for permanently installed pools whether they are above ground or below.
Is this fully true? As the code states:Those that are constructed on or above the ground and are capable of holding water to a maximum depth of 1.0 m (42 in.), or a pool with nonmetallic, molded polymeric walls or inflatable fabric walls regardless of dimension. So, if an above ground pool is over 42 inches deep, and meets this definition, it would seem a epb is not needed?

EPB has nothing to do with what the pool is made of. The epb has to do with keeping the voltage potential the same around the pool. If the pool is over 42" deep then it needs an Perimeter grid

But it says it’s doesn’t matter the size, if the pool falls under these specifications:or a pool with nonmetallic, molded polymeric walls or inflatable fabric walls regardless of dimension. This means, a bonding grid is not required. What am I missing???

What section are you reading? Where does it state that perimeter surfaces can be omitted when a permanent pool is used. I am talking perimeter surfaces not bonding of metal parts.. 680.26(B)(2)

Dennis, this is a brain-cloud day, but the pool described is a "storable pool" by definition and not subject to Art 680 Part II which includes 680.26

I guess I read the definition as saying the pool is considered a storable pool regardless of the 42? deep restriction (if the pool is inflatable). I?m reading the definition of storable pools. So would it still need a perimeter grid, if the definition says different?
