What are the electrical requirements for whirlpools?
The main pump/motor electrical connection consists of a single dedicated line with a 20-amp ground-fault circuit interrupter breaker (GFCI) and a 20-amp receptacle. For a unit with an in-line heater, a separate dedicated line, also with a 20 amp ground-fault circuit interrupter breaker (GFCI) and receptacle is necessary.
