Bonding A Double Insulated Pool Pump

Bonding is more complex with numerous pool specific rules in the electrical code.

Bonding a double insulated pool pump.

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. Grounding enables faster circuit breaker action and bonding ties conductive metal parts together so they have the same electrical potential. Together both reduce the risk of fatal shock. 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.

Check to see if the pump is listed as double insulated. When replacing the motor the installer must bond the new motor to the metal water piping system. Insulated ground wire is required for grounding pumps. Making a mistake grounding and bonding a swimming pool pump can be deadly.

If the motor is double insulated it might not have a bond lug. I took a little bonus footage from another video to make this one about pool bonding. However double insulated pumps are rare so that doesn t normally come up. 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.
