No bonding at pool. Help needed

[Stevenfyeager]

I need your help also. A pool was built 20 or 30 years ago. I have to replace the wiring to the pump. I noticed today, there is no (bonding) wire on the pump, at least outside on that screw, and NO wire anywhere going to a concrete rebar, or to ANYTHING. I don't know yet what they did with the romex bare ground going into the pump yet. I don't know what to do. Thank you.

There is not much you can do. Replace the wire and be done with it. Let the people know there is no equipotential bonding .

Why are you replacing this wiring and what are you replacing it with? Hint, there is a bit of a trap laid in this question.

I am planning on running individual conductors in flexible nonmetallic conduit, but not sure how to ground it. I want to run my new insulated ground to the ground screw on top of the motor housing, but then it would have to be out separate from the conduit. I havent taken the old wires out yet. They have a 12 2 romex on a romex connector into the motor. They are presently using that motor. Thank you

the equipment grounding conductor that runs with the other power conductors connects to a ground screw inside the motor junction box.

the external ground screw is for the equipotential bonding that you do not have.

my guess would be there is plenty of metal connecting the internal ground screw and the external one.

I am still curious why you are changing it out? is this indoors or outdoors?

Personally, i would be very suspicious that the person who installed this in the first place may not have known what he was doing and there may well be other issues. Once you touch it you kind of own it. It might have been best to avoid it, but now that you are 100% responsible for it you might want to write up a note to the customer as to anything else that needs to be fixed. They can still choose not to do it, but you have at least some cover if they refuse to do so.

All of the wiring is in metal rusted out conduit in concrete flooring and shorting out the lights around the pool. I am running new pvc circuits for lights and power to the motor because they asked me to get the lights working again. The only two wires that still work in the old conduit are the pump wires. I guess I could just leave the pump as is since it still works but I ran wires for it to that pool pump room since I have to run new circuits for the lights anyway. The pump is inside a room. I noticed that they used indoor 12 2 romex from the conduit to the pump. Yesterday noticed that the pump is on non gfi two pole CB in the house, which I plan to change. Thank you

I have found out that there are #8 bonding wires to each light fixture on brick pillars around the pool, would it be acceptable to connect to one of these and run a #8 to the pump motor to bond the motor? I assume these are bonded to the pool rebar, etc. I could run it in surface mounted conduit to the pool pump room.

In the 2005 NEC or before, can't remember, the swimming pool motor did not need to be on a gfci. Also what does the #8 bond wire to the lights connect to???? The pool pump is grounded so I am not sure that running the bond to those lights will help much if there isn't a perimeter bond, etc

I told the inspector today I would run a bonding wire to the pump form a bonding wire at a light,(#8 stranded insulated) and she said that would be good to do. I have to run about 50 feet, in conduit. Would it have to be solid #8 or could I run stranded? Thank you
