Steve:
I wasn't trying to blow you away.
OK...the 'bond' on pools is to create an equal potential. The pool pump motor, as well as all other metal (4 sq in or larger) must be 'bonded' with/by a piece of solid #8 copper wire. THIS IN NOT THE EQUIPMENT GROUND. It does not get connected to a ground rod. You 'bond' all the metal together.
Double insulated pumps, may exist, I personally have not seen any, although some people try to convince me that their pump IS double insulated.
The equipment grounding conductor IS NOT a 'bond', it is a grounding conductor.
Does the contractor you are using have a Permit?? Are permits required in your area??
IF so, then the local AHJ will assure you that the work was in conformance with the current NEC in your area.
As to 'leaving' a bond for a replacement pump?? Yes, that is a real good idea.
Take care & Happy Holidays
