Outlet Wiring
 
Hello,
I moved an existing wall outlet to a new location by disconnecting the receptacle and drilling new holes in the studs for the wire.
I reconnected the receptacle the same way, hot wire to gold screw, neutral wire to silver screw and ground to green screw. When the receptacle was outside of the box and the breaker on, everything was fine. When pushing the receptacle into the box and turning the breaker back on, there was a spark at the breaker and the outlet and the breaker flipped off. I made sure the hot wire connection was not touching the outside of the box.
The only connection that may have touched the sides of the box was the ground connection. Is it possible that could have caused the result? I thought the 'spark' was only possible from the hot connection touching something. It may have been possible that part of the hot wire below where th insulation was stripped touched one of the nails holding the box in place.
Does anybody have any thoughts?

you could have nicked the insulation while pushing it back into the box, causing a direct short to ground, therefore tripping the breaker and the arc.

After drilling holes in the studs for the cable,, did you sheetrock over them? It's possible one of the screws penetrated the bx. **it happens.
(Re: above post): did you use redheads (bx sheathing-end insulator shields)? They usually come with the roll of bx.

IF he drilled the holes in the right places (in the center of the studs) and IF he used the right drywall screws (1 1/4"), that would be quite impossible.

Obviously the two "IF's" are things only the OP can answer.

Usual practice is to put black tape around the receptacle, over the screws, before pushing it into the box. If there's a ground wire in there, (Romex?) it could have wound around and found the hot screw. I like to use a ground tail (green insulated braided wire ) if it's a tight fit.

May be use a multi-meter to check for short between hot and ground before turning on the breaker.... on next attempt...
