After discussing my system, they informed me that they had a technician who was currently in my area and could come in the same afternoon. Nate showed up early in the afternoon and was able to get my generator functioning within a few hours. He took the time to keep me informed during the process and we discussed my options for going forward with a maintenance schedule."

Electrical questions, answered by experts

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.

Appliances in your home that need dedicated circuits include:

  • Refrigerators and chest freezers

  • Electric ranges, microwaves, and toaster ovens

  • Dishwashers and garbage disposals

  • Washers and dryers

  • Heating and air conditioning units

  • Hot tubs, saunas, and water pumps

  • Sump pumps

  • Central vacuums

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.

The cost to upgrade an electrical panel ranges from $1,200 to $2,000, depending on the type of electrical panel you need and the size of your home. Amperage plays a central role in determining the cost, so calculate your home’s electrical load before purchasing. For example, a 100-amp and 400-amp panel vary widely in cost. 

It’s a great idea to replace and update outlets, especially if an outlet stops working. New outlets work well with modern appliances and devices. Over time, outlets become old and worn—they can even become damaged, cracked, and burnt if the wiring is old and outdated. Old outlets and wiring can cause smoke, sparks, flickering lights, and an electrical fire.
