Electrical questions, answered by experts

In most cases, line wires are located at the bottom of a panel or device, while load wires are located at the top. Line wires are generally black, while load wires are typically red or black. To tell for sure, you can use a multimeter or volt pen to test the wire. A live or line wire will always carry a charge, while a load wire will only carry a charge when it’s in use.

If you've ever tried to run your dishwasher while drying your hair, you’ll understand why dedicated circuits are essential for preventing blown fuses. Appliances that require more electricity than the circuit can handle could blow fuses, trip breakers, overheat, and risk an electrical fire. 

Having a dedicated circuit ensures that your appliance gets the current it needs without overloading the other circuits in your home.

Yes, blue wires can be hot wires in the U.S. However, they are less common in residential properties than red and black hot wires. Blue wires are typically used as traveler wires in three-way and four-way switches, as well as ceiling fans. They allow fixtures to be controlled by multiple switches, like when there are switches at the top and bottom of a staircase for the same light.

Compared to amps, volts, and watts, ohms are a different kind of measurement, though also very common. Ohms show the resistance of materials like wiring: How much they impede the flow of electrons. The reason household wiring is usually copper or aluminum is that these materials are affordable and also have lower ohms, which means low resistance/high conductivity.

In the majority of cases, you can replace an outlet with a USB outlet. USB charging receptacles install in the same spot as standard outlets and any electrician worth their salt is more than familiar with the replacement process. Additionally, it’s possible to replace yourself, but only if you have prior experience with your home’s electrical system, as it requires handling of wires.
