Ground wire on spa motor

| Just replaced an old pump motor that failed. The case of the old motor had a place to anchor a ground wire running from the panel. New motor does not have a place to anchor that ground. Is it necessary? Can I just fasten it to any bolt on the pump?
Thanks in advance for any advice you can offer! |

| You need a star type lick washer (internal or external, with internal a little better) to make sure a solid bond is formed that cuts trough paint and any contamination on the surface. |

| Thanks for his reply. Let me add some clarification, as I'm afraid my initial post was unclear. The old motor had a ground wire running from the case of the motor to a universal grounding bar on the panel (where other components were grounded as well). The new motor has no grounding connection at all. Does that mean none is required? I am not talking about the grounding of the entire spa - that is still intact. I'm talking specifically about the grounding of the small motor that runs the circulation pump. Hope that's clear! And again, thanks in advance. |

| "Does that mean none is required?" No.
It needs to be bonded just like the old motor. |

| This isn't the ground, it's the equipotential bonding required of all components and exposed metal of the spa. If something doesn't have a bonding terminal, you must install one. |

| "This isn't the ground, it's the equipotential bonding required of all components and exposed metal of the spa. " It follows the same rules for how the bond connection is to be made. |

| I wasn't arguing with you brick. It is NOT a ground. The requirement for it is different than for grounding (but the terminal is the same as you say). All the things required to be bonded need to be bonded with #8 solid. |
