DIY or call a pro?
A licensed professional should replace an electrical box; this job suits a professional rather than a DIY effort. Improper electrical work can create a significant risk of fire or electric shock, and a licensed electrician is required for work involving the electrical service panel or complex wiring. Before any wires are touched, power must be turned off at the electrical panel and a voltage tester used to confirm the circuit is dead.
