I have a 220V pump motor and also a spa air pump, as well as a 110v
pool light (which is on a standard lightswitch). I'd like to put them
all on GFCIs. For the light I could just install a GFCI switch, but
I'm not sure about the motors. Is the easiest way to just put in a
GFCI at my circuit breaker panel?
If the circuit breakers are a long distance from the pool equipment, and the
wiring is in an underground pipe, it may not be the best solution as tiny
pinholes in the conductors can cause the devices to trip. It would certainly
be the easiest solution though, and if it didn't work out, the wiring to the
pool could be changed with the panel relocated to the pool equipment
If the 120V circuit is pulled off the same line as the 240V make sure
the panel GFCI breaker
has neutral protection. The other type is only for 240V circuits
that don't use a neutral
and will trip in there is a 120V load across line and neutral.
