branch circuit for pool heat pump

[jimtheelectrician]

I am wiring a heat pump that will be used to heat above ground permanently installed pool. I see nothing in article 680 stating the use of an insulated ground on the branch circuit feeding this heater.I know that an insulated ground is needed for the motor as stated in article 680.21(a)1 but do not see anything similarly required for pool heaters. Would I be right in considering the use of non metallic sheathed cable sleeved in a pvc pipe as an approved wiring method for this application? Or is it just implied that art 680.21 (a) 1 is for all branch circuits feeding pool equipment.

If this is for the pool, I would consider this a "pool-associated motor" and would wire it accordingly.
