Bonding pool equipment


I need to connect a pump and a salt water chlorine generator power center to my pool's bonding grid. I understand that the grid doesn't need to be connected to a ground rod, but the pool subpanel does. Is it acceptable to connect the bonding conductors for the grid, SWCG, and pump to the subpanel's ground rod?

Thanks,

Sim

ground rod is not installed for a subpanel used only for swimming pool equipment.


The bonding wire for the pump and a salt water chlorine generator power can be connected to the existing bond wire for pool pump. You can use a split bolt to connect all the wires together

HUH???

Is it not still a remote distribution panel???

A ground rod certainly IS required for a pool panel (not that it will do much).

If the subpanel is mounted on a post and only used for assocciated pool equipment, than a ground rod is not required in my area.
Certain parts of NEC are removed in certain areas of the country, that is why it is always good to ask the AHJ in your area.
The NEC can be qouted but it may not apply to you area.

Thank you both. I'll email the VT codes officer, but it seems reasonable to go ahead and put the ground rod in (since I already bought it).

Is it dangerous to connect the bonding grid to the earth ground, or just unnecessary?

The NEC states a grounding electrode be installed when a panel is installed in a unattached structure. The pedestal mount being used IS a structure in it self and therefore is an NEC requirement.

It is extremely important that you have a equipotential bonding grid installed. If your pool is not new and passed the initial inspection, then I see no reason to tear up the coping or concrete floor. If this a new construction, you better get a licensed electrician involved. This is a matter of life and death.

The pool is new, I observed the construction, and the bonding grid is installed. The builder designated a spot at the equipment pad where driving a ground rod should not hit any piping or sever any bonding connections.

Edit: I'll qualify that - I know that they ran #8 bare copper wire to all the metal pool and deck parts (light niche, ladder rail sockets, several places on the rebar, etc., and brought that wire out of the ground at the equipment pad next to the pump. They also recommended connecting it to a ground rod and designated a spot for it at the pad, but that seems to be unnecessary.
