I was changing 4 outlets from beige to white, put all the wires back in the exact place they were in from the beige outlet to white. They all have a red,black,white and copper wire. Flicked the breaker back on and no power-turned it off immediately check the outlets that were removed and noticed that there was a brass tab that had been removed on the original outlet. Went back to all the outlets as this had been done to all 4 and removed the tab. Turned the power back on and one of the breakers sparked. Power is turned off to that breaker. Not sure what to do now. 2 of the outlets work.

There was a short circuit and the breaker tripped. Sometimes they will spark inside when they trip.

Go back to the dead receptacles and check for touching wires.

Found the problem-white wire had come loose-Thank you for helping.
