"Gridwise installed a hardwired Level 2 charger for us and it was refreshingly easy. We did a quick video inspection, got a clear estimate, and then they showed up on schedule and knocked it out. The wiring is clean, no mess left behind, and they took a minute to explain the configuration/settings so it made sense. After dealing with contractors who disappear or complicate everything, this felt efficient and professional. Would use them again."

"Steve and his crew of electricians did a fabulous job. They basically replaced the entire house’s electrical, all new switches and outlets in addition to all the new light fixtures in every room. They showed up on time, did what they said they would and addressed every issue encountered in the rehab. In addition, Steve was great helping me decide what to put where. An overall excellent experience. I would HIGHLY recommend Warner Electric for any electric job."

"Elvis, Kargene and team were absolutely fantastic. We hired them to do a panel swap/merging as well as a transfer switch implementation. Kargene was super communicative and really clear and the whole team was incredibly flexible, accommodating and professional. Zarco's Electrical is now my go-to for all of my electrical needs moving forward."

"I had 2 ceiling fan/lights installed in the bedrooms. Installation included 2 new circular circuit boxes in each bedroom ceiling. In addition, I replaced the kitchen ceiling light with an LED fixture. The 2 workers were very polite and professional and worked quickly and efficiently, in addition to being respectful of my personal belongings."

Electrical FAQs, answered by experts

Most household circuits can handle about 70 strings of 50 standard mini lights, or up to 600 strings of LED lights, which consume less power than the incandescent variety. Make sure to factor in any appliances also running on the circuit.

Depending on complexity and materials, costs range from $150 to $500 per fixture.

With AC wiring, which is the kind most likely you’ll find at home, the black wire is “hot,” and the white is “neutral.” The bare or green wire is considered the safety ground wire. If you encounter DC wiring, it’s relatively easy to tell positive or negative wires apart. red wires are used to indicate positive voltage and black wires indicate negative voltage.

Be careful not to drop your voltmeter or multimeter. Even a small fall can affect the tool’s ability to measure with accuracy. Always store your tools in their cases in a cool, dark place. Also, avoid touching the probes to each other while they’re connected to a circuit or another electrical component, and never tamper with anything inside the device.

Upgrading a two-prong outlet to a three-prong outlet typically costs between $20 and $50 per outlet if the electrical box is already grounded. However, the cost can increase significantly if the system is not grounded, as this may require grounding the box or upgrading your electrical panel. Electricians generally charge between $50 and $100 per hour for labor, and the total cost for a more complex installation could range from $130 to $300.
