dtontarski Posted January 16, 2010 Report Share Posted January 16, 2010 I observed a hot tub install today and have a question about overcurrent protection. This was wired with four 8-gauge stranded copper conductors routed through rigid conduit and protected by a 50 amp GFCI circuit breaker. The standard practice is that 8-gauge requires overcurrent protection by a 40 amp circuit breaker. This stated, it is common for AC condensing units to have a minimum circuit ampacity requirement that allows for the use of smaller gauge conductors. Do hot tubs have similar requirements. Do they have similar tags as AC units which specify the minimum circuit ampacity and min - max circuit breaker requirements? There were no access panels on the skirting of this tub that supported the observation of manufacturer labeling. Any advice would be appreciated. Thanks.
