"Lawrence did an outstanding job from start to finish. He installed a dedicated electrical circuit for our new mini-split in my kids’ room, repaired and organized several electrical wiring issues around the house, and installed an exterior fan—all with exceptional craftsmanship and attention to detail. He took the time to explain everything, kept the work area clean, and made sure every detail was done right. His professionalism, reliability, and pride in his work really stood out. If you’re looking for an honest, knowledgeable electrician who genuinely cares about quality, I highly recommend Lawrence. I’ll definitely be calling him again for future electrical projects!"

"Kevin and his whole team were great! They arrived on time, gave us a thorough walk through and estimate. They were far and away the most professional. They were aware of our needs and made suggestions that made the process even smoother and the end result even better. We have already recommended them to friends of ours that are in need of an electrician. If we need any electrical work done in the future, we will definitely use them!"

Electrical FAQs, answered by experts

The National Electrical Codebook indicates that there should be at least 6 inches of wiring in the breaker box for connecting purposes. When in doubt, err on the side more, because you can always cut some wire off but you can never add it back on, and if you don’t have enough you may struggle to finish wiring your breaker box properly.

If you need to run a wire from the meter to the breaker box, start by turning off the power using the main switch to avoid injury risks from live wires. Then, locate the ground wire from your meter and connect it to the ground bar of the breaker box. Connect the neutral wire using the same method to improve your circuit efficiency.

Next, locate the hot wires running from the main switch to the meter. To connect them to the correct terminals from meter to breaker, unscrew the nuts of the breaker hotwire terminals, insert the positive hotwire, and ensure it’s firmly attached. Finally, secure the wires with electrical tape and wire tie cables before re-securing your breaker box. Keep in mind that this process can be dangerous, so don’t hesitate to hire a local electrician.

The standard copper wire gauge to use with any 30-amp circuit is a 10-gauge wire. The National Electric Code specifies a 10-gauge wire with appliances like water heaters running on 30 amps. If you try to use a smaller gauge wire, such as a 12 gauge, with a 30-amp breaker, you run the risk of the wire overheating and melting or causing a fire. Because of the safety hazards, the gauge of the wire is not an area to try to cut costs when connecting a 30-amp breaker to a water heater.

An outlet can start a fire if it has blown a fuse, or is sparking, overheating, or smells burnt. Prevent electrical fires by unplugging the device connected to the outlet and hiring an electrician to determine and fix the outlet’s issue. If the outlet stays hot or isn't working, you should fix it.

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.
