Cliff I also agree a GFCI is not required for this application.

However just because something is grounded does not exclude it from GFCI requirements.

Think of the GFCI as a back up to the EGC.

The GFCI rule that went into the 2002 NEC for commercial kitchens is a good example of this.

All 120 volt 15 and 20 amp outlets must in commercial kitchens must have GFCI protection.

That rule went in as people had been killed by appliances that the EGC failed on.

Another example is the 2005 NEC requirement that vending machines have GFCI protection again it is a back up to the required EGC.

This is all for plug and cord connected appliances, hardwired and the GFCI regiments do not apply.

Same for a pool pump for that mater.
