I am installing a new whirlpool bathtub at my girlfriends place and
was checking things out. The electrical is gfi'd in the panel and has
a dedicated 20 amp circuit feeding it - so far so good.

In addition, the old tub had a big ground wire run from the water
valve to a ground strap on the motor assembly. My Jacuzzi and pool
pump all have a separate ground run from the panel to them.

This motor does not have a provision for a ground strap anywhere on
it. The difference is that all the other assemblies I have wired are
hard wired. This one has a molded three prong plug on it.

I was wondering if I should jury rig something to ground it to the
motor somehow, or maybe to the junction box that it plugs into (Of
course the junction box is already grounded from the panel). To me it
just seems like an extra safety precaution that could not hurt.

Comments?

It's fine. The motor will be grounded through the plug. On your pool and
Jacuzzi, there's no need for the #8 solid bond to return to the panel
either. All the metal parts associated with the pool have to be bonded
together
