On another forum this was posted by someone that owned a Jacuzzi tub, they claimed this was what the instructions said.
MOTOR/PUMP: 115 VAC, 3450 RPM/7.8 AMP, 60 Hz Single phase.
ELECTRICAL SERVICE REQUIREMENTS:
115 VAC, 15 AMP, 60 Hz. Requires dedicated separate circuit.
Given this infomation would it be correct to feed it with a 20 amp circuit?
