pool bonding question

[justin1795]

we are getting our inground pool repaired. it was here when we bought the place. I removed the old pump the bonding wire was broke off..the instructions state to connect a 8awg bonding wire to all metal parts within 5foot of inside walls of the pool.
our pump sets back 20 foot from the pool. the only thing I can see to connect it to is the conduit that runs to the pool light. anyone have any feedback on this

I would call a professional electrician with experience in pools. Article 680 of the national electrical code is a good place to start, but you may have local codes that are stricter.

improper bonding around a pool can be very deadly.

You need to find and or dig up the missing #8 bond wire that was originally connected to the pump motor and reconnect it to the new pump.

The pool bonding was done underground when the pool was initially built and all the necessary bonding requirements were met at that time. Diving board, underwater light, hand rails, rebar etc. All this was done with a continuous #8 bare solid bonding conductor. The continuous #8 was then run over to your pool equipment and bonded to the pump motor and heater if so equipped.

You must find the wire and reconnect so all has the same ground potential, its called equipotential bonding.

This is an absolute must!

Good Luck

I called a pool guy out today. he said he didn't see any bonding points on the pool and that the case should just be grounded.

You need a electrician that is qualified to do pools to take care of this, not a "pool guy", the stakes if this is done wrong is too high. Is this is a older pool?

 

[justin1795]

yes its around 30 years old.

I thought the bonding (not grounding) wire took care of low level voltages from areas at different potential that could cause tingling from just a few volts.

Apparently I'm the only person in the local PA area to run bonding wire for my above ground pool since no one stocked the items I needed to do it!

What is the pool light conduit made of?

How is the pool constructed?

So you can't find the other end of the bonding wire?

I would think that it would have been bonded 30 years ago. I have a big concrete pool from the 50's -- so a bit older than your's that was not bonded. All the pumps and electric are least 25 from the pool.

When I replaced the concrete surround about 20 years ago I was surprised I did not have to bond the old pool -- I did bond together what I could ... but I was advised to not tie it back to the pumps. It was all inspected -- I'm in NJ We used plastic to run the new light conduit.

All the my pumps are grounded to the Intermatic timer sub-panel .

the pool light is steel conduit. our pool has steel wals with a 2 foot cement walkway around them. the walls are about 36 in deep then its a sand bottom with a viynal liner. I pulled the old pump out to take a look at it. the bonding wire is still attached. the other end looks to be cut and slightly shiny. I wonder if they had it to a ground in the panel. (we purchased the house with the pool trashed) our pump is about 22 to 25 foot from the waters edge also.
