"Michael showed up right on time, removed the old light fixture, installed the new one. He cleaned up the small mess that was made with the project and took the old fixture out with him when he left to dispose of. The pricing was fair and I have absolutely no complaints with the technician that came to do the project or Supreme Electric & will use them again on future projects."

Electrical questions, answered by experts

Three-way switches are only replaceable with three-way switches. A single-pole switch won't work if you replace one or more of a pair of three-way switches. By electrical code, three-way switch configurations are necessary at the top and bottom of a staircase between residential floors.

Yes, a faulty or broken light switch can be a serious fire hazard. Malfunctioning switches, often due to loose connections, exposed wiring, or overheating, can cause sparking or arcing. If you hear a crackling, popping, or hissing sound when you use the switch, it indicates live electricity arcing inside, which is a significant hazard that can ignite nearby flammable materials. If you suspect your light switch is faulty, turn off the power to that circuit at the breaker and contact a qualified electrician to remedy the issue.

The best place to put an electrical outlet depends on your needs. A good rule of thumb is to install outlets every 6 feet in large rooms. Hallways over 10 feet long need one electrical outlet minimum. 

If you find yourself needing extra plug-ins for all of your gadgets, you may want to increase the number of electrical outlets in your room. When adding outlets, keep in mind that older homes could have outdated electrical panels. In these cases, you may need a pro to upgrade you from 100-amp to 200-amp service before increasing the power load.

Soldering is a reliable and durable way to connect wires, but it isn't the only method. Nowadays, professionals often crimp the connection instead—although this requires a higher degree of skill than soldering.

When converting a standard 120-volt outlet to a 240-volt outlet, the only components you can typically reuse are the existing electrical box and the hole in the wall. Everything else—including the wiring, breaker, and receptacle—should be replaced to ensure both safety and efficiency. Appliances designed for 240 volts have different plug configurations that won’t fit into a standard 120-volt outlet, making it necessary to install a compatible 240-volt receptacle. This design helps prevent overloading or underloading the power available to any one outlet or circuit.
