Sure, and when it trips you have a fine old time figuring out what
caused it and where the electrical leakage to ground is taking place.
My house was wired that way when it was built for us.
Example; they used one GFCI for the outlets in two adjacent bathrooms
and then fed the bathroom vent fan switches from the downstream side of
that GFCI. So, once in a while when things got fairly steamy in a
bathrooms, and the fan was powered, a few hundred microamps of leakage
in the fan motor would trip the GFCI. Bah!
I changed things over so there's a descrete GFCI outlet everywhere one
is needed, so the cause of tripping it is obvious because it can only be
what's plugged directly into it. Only exception are the three kitchen
counter outlets which are fed from a single GFCI breaker in the panel.
