An island in my kitchen has two circuits - one for the GFCI outlets and
one for the dishwasher. There is one 12/3 cable coming out of the
slab. When I turn on either the breaker for the outlets or the breaker
for the dishwasher both the red and black wires go hot. Is the 12/3
wired wrong at the breaker box? Thanks for any help.
