Jim was very professional, friendly and informative. He knew exactly what to do and did all the jobs quickly without disturbance.

We initially hired Mr. Electric do the 200 amp panel upgrade but quickly realized what a great electrician we had so we asked for a quote to do other jobs in our home. The quote was very fast and Tom worked with us to get it in our hands and worked around our schedules to get the work completed. We are really pleased at all the work and will gladly recommend Mr. Electric to all. We will always use this company for all things electrical!

Electrical questions, answered by experts

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.

Wire color codes vary depending on the region. For instance, the United Kingdom has updated its wiring codes to match Europe's color system. The United States wiring color code is different, as is Australia's. Because the color code system isn’t universal, it’s essential to hire an experienced electrician to perform any electrical work to ensure it is done correctly.

It depends on where you live. Some cities may require a permit for electrical work, while others don’t. You’ll need to call your city’s building department to determine if you’ll need to apply for a permit or not. If a permit is required, you’ll likely have to pay a fee for it. 

The common, marked as COM or C, is one of the terminals found in your light switch. It houses the live wire that supplies the input voltage. The other terminals, marked as L1 or L2, are the outputs to the light fixtures. Depending on if you have a one-way or two-way switch, you’ll either have just an L1 terminal or both an L1 and L2 terminal.

You should never use a plug with burn marks because it can cause a fire or even an electrical shock. The burn marks could be caused by a dangerous underlying electrical problem, so it’s important to call a qualified electrician right away.
