Electrical questions, answered by experts

You can have power but no lights if the light switch is damaged. A damaged light switch is often caused by regular wear and tear or loose wires. In addition, simple problems such as a burnt-out light bulb or an unplugged lamp could be the cause of not having working lights.

Yes, many providers offer wiring upgrades as part of their services. Confirm with your contractor.

How far you can run underground electric depends on the wire gauge (generally AWG) and the circuit voltage. Too much voltage drop in an electrical circuit can negatively affect performance, so the smaller the voltage drop, the better. Ideally, it shouldn't exceed 3%. The smaller the wire and the longer the run, the more significant the voltage drop. 

For example, with a 120-volt circuit, you can run 60 feet of 12 AWG cable without losing more than 3% voltage. With a 240-volt circuit, you can run 120 feet of 12 AWG wire while maintaining a voltage drop of 3% or less.

To install an outlet from existing wiring, you’ll need to choose a location where you can already access existing wiring. The easiest way to do this is to install an outlet on the other side of the wall of an existing outlet. 

Since the wiring is already in place, all you have to do is connect a new cable to the existing wiring and then connect the correct wires through the wall—to the new electrical outlet. Place your new outlet into the opening in the wall and then connect the correct wires to the appropriate terminal screws.

While you might not need to put lights and outlets on separate circuits, some local codes may require that you use separate circuits. Installing a separate circuit helps prevent total darkness in your home when your receptacle outlets take on too much power and blow a fuse or trip the breaker. It also costs less and is easier to simply install a new circuit.
