Wall current --> GFCI --> 110 V to 220 V transformer --> equipment
Is it true a GFCI on the other side of an isolation transformer is
useless?
If there is a ground fault in the equipment, will the GFCI trip the
circuit?
It doesn't in my room and it makes me nervous, but maybe the GFCI
is faulty.
I should get a 220 GFCI,
I know from experience that a GFCI rated for 110 V releases all the magic
smoke* that makes it work when trying to trip a 220 circuit.
Second, GFCI circuit breakers are expensive, but they can be cheaper than
rewiring every outlet, especially if the boxes are too small to
acommodate the larger GFCI.
