When replacing electrical outlets or wall plugs consider more than just turning off the circuit associated with that particular plug. If another circuit is running through the same box and it is still live and you separate the white wires or open them up you may get shocked because power is returning to ground from the other circuit. If not completely sure turn the main circuit breaker off for the entire house.

It is always best to hire a licensed electrician or electrical contractor to do even what seems to be the most minor operation.
