Electrical FAQs, answered by experts

Professional services ensure safe installations, reliable repairs, and compliance with codes emphasizing safety in electrical networks.

On average, it takes from four to eight hours to replace an outside electrical meter box, not including rewiring. It will take a few more hours if the project requires pros to do any rewiring work. Consult your local electrician about a time estimate for your specific project.

When wiring a switch, the power typically comes into the receptacle first. The neutral wire goes straight to the outlet, while the hot wire is split. You'll need a wire nut to splice the hot wire back to one of the receptacles, but you will also tie another wire into that same wire nut and run to the switch. That way, you can control the flow of electricity to that particular receptacle by turning the switch on and off.

For a 200-amp underground service, you need a minimum of #2/0 American Wire Gauge (AWG) copper or #4/0 AWG aluminum or copper-clad wire. Don’t forget that, at minimum, you’ll need to use a 1 1/2-inch schedule 40 or 80 PVC conduit to successfully run a 200-amp underground service.

If you’re replacing wires from an electrical meter box to the breaker box, you may also consider installing a new meter or replacing or repairing the breaker box . You can tell if the circuit breaker is bad if you’re dealing with tripping or worrisome burning smells. Both projects should also be handled safely by a licensed electrician.
