"Chris has been to my home twice. The first time was to trouble shoot a circuit breaker that kept tripping, and he was able to isolate the problem to a faulty circuit breaker. The second time was to install a bathroom fan. Both times his work was great, and he was pretty easy to get ahold of, and was good about scheduling. I will definitely be returning to Chris again in the future for my electrical needs, and would absolutely recommend him to anyone else looking for an electrician."

"Matt and his team were professional and friendly. He communicated well and was punctual. I had him put in an EV Charger out to my driveway and also needed to upgrade my electrical wiring which became more difficult than expected but Matt honored our agreed contract and had even saved us some money on figuring out a better solution. I highly recommend Matt and his team for any electric service."

"I met ElectriChris, Inc (Chris David) through an online referral service in March, 2018. From 2018 through 2024, Chris has done nine separate electrical projects for me. I am definitely a satisfied customer. Chris does neat, professional work. He knows the code and his work meets the code. All of the projects that Chris has done for me were done while we occupied the house. He cleans the work site at the end of each day, and the disruption to our house was kept to a minimum."

Electrical questions, answered by experts

No, it’s extremely dangerous to cap off live electrical wires. Working with live wires puts you at serious risk of electric shock, which can cause injury or even be fatal. Whenever you need to cap off electrical wires or complete any electrical work in general, it’s essential to shut the power off at the breaker before you begin.

This depends on how many outlets you have and the current status of your electrical system. The cost to ground an outlet clocks in at $75 to $480 per outlet, so multiply that by the number of outlets in your home to arrive at a rough estimate. However, this is for simple projects with no obvious issues with the system. Your final bill could vary widely from your calculations.

A gas stove doesn't always need a dedicated circuit. Unlike an electric range, which uses 240 volts and requires a 240-volt receptacle, a gas stove only uses 120 volts. In some cases, your electrician will need to replace the existing two-pole circuit breaker with a single-pole circuit breaker as well as swap out the existing 240-volt receptacle with a 120-volt replacement.

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.

A voltmeter measures the voltage of AC or DC electrical current. Unlike a multimeter, measuring voltage is a voltmeter’s only function. Voltage is the potential difference between two points within a circuit. Measuring voltage with a voltmeter can help identify wiring issues or determine whether a battery is dead.
