So... I tried swapping two outlets in my kitchen, and tripped the entire power panel!
The old outlets were wired with FOUR wires: red, black, white, bare.
I wired the new outlets using the same scheme:
- Red to one of the HOT terminals
- Black to the other HOT terminal
- White to one of the terminals labelled WHITE
- Bare to ground
AFAIK, these were not GFI outlets. Or, at least are no test\reset buttons on the old outlets.
Also, each outlet are on there own circuit, with nothing else on the circuit.
Something else that's probably key to my scenario is that each of these circuits are "spanned" on the power panel: 15 amps + 15 amps
In the picture below, one of the outlets is the only thing on "24 and 22", while the other outlet is the only thing on "20 and 18".
I'm pretty sure I wired the new outlets correctly. But when I turned their circuit breaker back on - POOF - the entire board tripped and all the power in the house went off!
I'm starting to think these 15A+15A circuits require a special outlet capable of handling 30 amps, and that the outlets I tried to installed were "standard" outlets, which I think are rated for 15 amps.
Am I right? Do I need to buy a special outlet?
Or did I indeed wire these incorrectly?
UPDATE: Thanks for the replies! I got 2 new outlets and broke the tab off (hot side only), now everything works. For future visitors, this video explains this situation, and corroborates the advice the responders posted:
