have to go on a bid for a above ground pool install. Reading up on code it appears that if the waterline on the pool is not greater than 42" there is no need to bond if pump is double insulated 680-30. But if it is greater than 42" then you must bond. Is there fittings for bonding above ground pools? do you have to bond every leg or just a one point at pool? 680.26B4 (2002)states that if a double insulated pump is used you still must pull bond wire to pump and connect to EGC of motor circuit. I can see why you pull bond wire in case a replacement non double insulated pump is used as a replacement but it doesnt seem right to tie bond wire to EGC for insulated pump. Any info or comments would be greately appreciated. This is my first post with the new format. Still trying to get used to it

Re: pool bonding

Four,


Welcome to the board. Here in NJ when we look at section 680 C of the NEC it talks about "Storable" pools. To us that means if you take it down for the winter and put it up again next spring. That would be a storable pool. If you leave it up all year long, it isn't and it must meet the bonding requirments of 680, unless the motor was double insulated, then bonding is not required. When in doubt ask the AHJ who will be doing the inspection. It is easier to get the correct answer from them and do the job once.

Re: pool bonding

The bonding that your talking about does not have to be pulled back to the panel and is not for fault current but to bring the voltage potental between metal that may be contacted by person's down to a safe level and if the pump is double insulated then you are to connect this bond to the egc that you pulled to the pump motor. but if the pump has a bond connection then all you are required to do is connect it to it. the egc is there to carry the fault current not the bonding conductor. the bond conductor has to connect to metal ladders pool walls and or post slides and any other metal that could have stray voltages form on it.

As it says in 680.26 including the fpn
