Bonding A Double Insulated Pool Pump

But it s not practical to tie the ground system to the bond field on ag pools using a double insulated pump and serviced by a 2 wire feeder protected by a gfci. There s some possibility that a double insulated motor which didn t have a bonding jumper installed might be replaced by a motor that isn t double insulated resulting in a noncompliant installation. In this case which i understand to be your case i would recommend installing a full driven ground rod immediately adjacent to the pool preferably in the dampest location around the pool and tying the bonding wire to that ground rod.

Making a mistake grounding and bonding a swimming pool pump can be deadly.

Bonding a double insulated pool pump.

However double insulated pumps are rare so that doesn t normally come up. Bonding is more complex with numerous pool specific rules in the electrical code. If the motor is double insulated it might not have a bond lug. When replacing the motor the installer must bond the new motor to the metal water piping system.

The goal of bonding is to prevent electrical current from flowing through people who are in or touching the water. Grounding enables faster circuit breaker action and bonding ties conductive metal parts together so they have the same electrical potential. A listed cord and plug connected pool pump incorporating an approved system of double insulation that provides a means for grounding only the internal and nonaccessible noncurrent carrying metal parts of the pump shall be connected to any wiring method recognized in chapter 38 that is suitable for the location. Check to see if the pump is listed as double insulated.

Together both reduce the risk of fatal shock. Insulated ground wire is required for grounding pumps. I took a little bonus footage from another video to make this one about pool bonding. If it is double insulated you don t have to bond it but you do have to provide a bond wire that can be used if a replacement motor is installed that is not double insulated.
