I remember working with a guy when we were going to pull some more wire into a conduit. After he loosened the outlet, I asked about killing the power to the circuit.
"Good idea" he replied, pulling out a screwdriver... then placing it against the "hot" terminals on the receptacle, he intentionally placed it to short to ground against the box.
"POP"
"S'dead now" he replied, picking up the fish tape...
