Pool Motor Bond

[fc]

Inground cement pool with no metal parts no diving board no ladders. Has pavers around pool with no wire mess. How and what do you bond the pump motor to? The pump has EGC installed with the circuit in pvc. The pool is 200' from the house.

Re: Pool Motor Bond

The question is not wht to bond the motor to. It's what do you bond to the motor. Sounds like nothing in this situation. No rebar in the cement?

Re: Pool Motor Bond

No rebar they have pavers around the pool.

Re: Pool Motor Bond

Hello fc,

Are the pavers already installed, without a # 8 solid bonding conductor installed around the 'pool area' ?

Re: Pool Motor Bond

What is a " paver " ?

Far-Fetched - - -, T110.34(A) Condition 2, considers a cememt wall as a grounded surface (conductive), but then, it is not metallic as per 680.26.

Re: Pool Motor Bond

Pavers are installed and no wire mesh under them. There is no bonding grid anywhere. I think as long as the circuit that's feeding the motor has a EGC that all that can be done. There is nothing metal around to cause any problems except for the motor and that would be grounded with the EGC. I think?

Re: Pool Motor Bond

If this is an inground concrete pool, then there should have indeed been rebar in the pour to strengthen the pour. I believe that this would be true even with gunite, [shotcrete]. We have a pre-opour inspection for such things; 'cause if they missed it, they kinda screwed the pooch. This would have caught all of the metal fittings such as metal forming shells of fixtures, [ although all I see nowadays is PVC], ladder sockets, water movement grates, diving board sockets, if they existed, [I know you said they didn't. But at least the rebar in the pour.

Re: Pool Motor Bond

Fc there might be pavers around the pool but the pool is made with cement and should of had ether wire mesh or rebars installed and this is what should of been bonded. since the cement can conduct current there should of been a bond to it. maybe there is a way to dig down and get a hold of somthing metal that might ran through the cement?

Re: Pool Motor Bond

Cement pool without rebar or wire mesh ??????????
I have seen 100`s of pools built and have never seen a cement inground pool without wire mesh and rebar......It is essential to the integrity of the
pool,pavers have nothing to do with it. How was a final inspection passed without a pool bond ?????? #8 bare to rebar as required ,niche light if brass nippled,back to pool panel ,and to pool pump,s.

Re: Pool Motor Bond

The pool is 45 years old and I found the existing pump bonded to a ground rod right next to the motor. I will have to dig up around the pool and try to find rebar or mesh from the pool cement.I would hate to start chopping the walls of the pool. There is no light, ladders, or diving board. The only metal would be rebar/mesh for the walls of the pool.

Re: Pool Motor Bond

In my 'haste before going to work' of my previous post, I should have used " T 110.26(A)(1) Condition 2" and not the over 600 volt table.

Re: Pool Motor Bond

When they poured the concrete for the pool, they might have used fiber mesh with a six and half bag mix? Ask for a load ticket from the concrete contractor. The other option is to bore a hole and used a tv scope. Example they pour a basement without the underground plumbing being inspected.

Then if they used fiber mesh, go to the local ahj and ask to see the file. There might be a report on the materials they used?
