Electrical questions, answered by experts

Inverter generators are designed to turn on the engine when your appliances demand more energy. This is in contrast to running at full capacity as soon as they’re turned on, like a standard portable generator does. So long as the wattage rating is high enough, an inverter can power a refrigerator just as well as a traditional generator.

Yes, electric fences need power to operate. They are powered by either a battery or an electrical outlet. In heavy snow or extreme rain, or if the power goes out, your electric fence might stop working. Knowing how to test an electric fence is important for figuring out if the fence is still functioning properly.

You don’t need an electrician to change an outlet—but that doesn’t mean you shouldn’t hire one. Working with electricity can be dangerous, not only for you but also for your home and the members of your household. There’s the risk of electrocution, poor wiring burnout, and electrical fire. When you hire a licensed electrician, you’ll have peace of mind knowing that your electrical outlets are installed correctly and up to code.

Window ACs use 500 to 1,400 watts per hour of electricity, while mini-splits use 500 to 700 watts per hour. However, if you need to cool multiple zones in your house, your mini-split can use as much as 2,000 watts per hour. How often you run your system will impact how much electricity you use (and how much you pay per month).

You can bury underground electrical wire six inches deep—but only if you use a rigid metal electrical conduit. For rigid, non-metallic conduits, bury the wire at least 12 inches deep. If using an underground feeder cable rated for direct burial, you'll need to place it at least 18 inches deep, as it has no conduit for extra protection.
