I turned off ALL circuit breakers in the panel.

I then pulled out the duplex receptacle from the electrical box in my garage and removed the wires.

I then attached the black, white and ground wires to a new duplex receptacle with two USB ports.

I was shocked by another white electrical wire in the box. Why wasn't that circuit controlled by a circuit breaker in the panel? Should the white wire have power?

Sometimes two different energized circuits wind up sharing a neutral and that could be the reason you got a shock off the white neutral wire. o_O
