An electrician can install the 240V wire and 60A neutrally protected GFCI. Your main breaker box will also need to have a 60A breaker. Your QCA Spa is hard wired through the floor or side wall of the spa cabinet directly into the spa's control pack. The GFCI is installed next to the spa on an exterior wall at least 5 feet from the spa water.
