Customers say: Quality work

"Steve came out on short notice on a Saturday to install my water heater. He returned calls, showed up when he said he would, did the work quickly and professionally, and saved my family from a weekend of cold showers in February. He will be our go-to plumber from now on. Highly recommended."

"Switching from a gas car to an EV entails a sharp learning curve. Having a charger installed with an outlet that didn’t previously exist isn’t an easy job. Josiah installed a new outlet, changed the paneling, and set up my charger in two hours. It’s hard enough just to get an electrician to show up. Make your life easier and just hire Josiah to get the job done right."

Electrical questions, answered by experts

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.

Your outlet should be a ground-fault circuit interrupter (GFCI). These outlets will cut power off in the case of an electrical fire, keeping your home and family safe. Extension cords can also be GFCIs. A local electrician can replace older outlets with GFCIs, if necessary.

Wiring can last anywhere from 50 to 70 years, but all kinds of mishaps can occur that reduce the lifespan of your electrical wiring, including severe weather conditions, pests, and even faulty wiring. Keeping a preventative maintenance scheduling and hiring an electrician for an annual electrical inspection will keep your wiring system around for as long as possible.

Yes, in a new home, ground wires are mandatory. Some older homes may not be grounded, but if you decide to renovate, you will need to have your electricity grounded at that time. Remember, grounding helps keep everyone in your home safe from sudden electrical surges. It’s best to hire an electrician to inspect and work with your home’s wiring.

No. Do not use a 14-gauge wire on a 20-amp outlet. A certified licensed electrician would know that the National Electrical Code (as per Section 240.4(D) subsection 3) requires 14-gauge wires to be used with a maximum amplitude of 15. Therefore, you should only use 12-gauge wires on 20-amp outlets.
