how long should a hot tub GFI breaker last
1 Under normal conditions the hot tub GFCI circuit breakers should should be checked using the TEST Button, and then reset normally. 2  Typically a hot tub GFI Breaker will last for several years under ideal conditions. I filled the tub with fresh water and hit the breaker. 2  You can hear electrical noise in breaker like it is shorting, then breaker kicks off. 3  Even if there was a short in the spa, the breaker should just kickoff without the noise. 4  It sounds like two wires arcing, there is no smell and the breaker is not melted.
