Electrical Wiring Methods for Replacing Outlets
Electrical Question: I replaced some outlets and now circuit breakers are tripping off, what did I do wrong?

I have 6 outlets in a room that I replaced. The bottom half of the outlets are wired separate from the top half. When I wired the light switch I noticed it had two black wires on the bottom screw and one white wire on the top screw. I turned the power on and the light came on. At first I did not touch the switch. Then I turned on the switch and the main breaker blew along with 3 other circuit breakers. What happened?

This electrical question came from: Royce, from Carlton, Minnesota.
