ABSTRACT:
A control system for a bathing installation which has one or more electrically powered devices. A line voltage service is connected through a GFCI to power the electrically powered devices, the GFCI adapted to interrupt the service upon detection of a ground fault. A trip circuit may induce a ground fault and trip the GFCI in response to a trip signal, thereby disabling application of electrical power to the electrically powered devices. An electronic circuit is responsive to a fault condition for generating the trip signal.
