A.GFCI is an acronym for Ground Fault Circuit Interrupter. GFCI protection is necessary in case anything electrical should allow electricity to leak to grounded metal in connection with the spa. This is especially possible if after years of use a heater element should rupture and the ground wire (that may or may not have been originally connected) should happen to become disconnected. A GFCI will sense this leakage and shut the voltage to the power pack off. As of January 1, 1994, all equipment packs used with a spa or hot tub must be protected by a Class A Ground Fault Circuit Interrupter. This is called for in the N.E.C. code book in paragraph 680-42. If the equipment has a GFCI built into it, that GFCI may only protect certain components such as the blower, light ozonator, and sometimes the pump. The GFCI may not provide full protection, especially if the unit is wired for 240V service. To be sure, have a qualified electrician study the wiring diagram that came with your unit (or th
