I recently redid an upstairs room in my house and installed new
three-prong outlets in each of the fixtures. Each of them has been
grounded. Two of them are on one circuit and work fine. The third
one appears to be wired to a wall switch.
The switch that was already installed is, according to the printing on
it, is a three-way five-amp switch. Only two wires connect to this
switch (black and white according to my home's wiring code; I'm in the
USA). When I throw this switch, one of the circuit breakers
downstairs trips and lights in an adjoining room turn off. I was
worried that the switch might be wired in backwards, but that doesn't
seem to have any effect.
Nothing is plugged into any of the outlets in this room. Is there
something obviously wrong here?
