"Nathan of N3 Electrical Service did an amazing job for us. He was always prompt, communicated effectively and did a quality job. He installed a new 200 amp panel and new wiring for a kitchen remodel. Once the project was completed, the county inspector even complimented the quality of the work"

"Great experience! Showed up the day after posted the project. We had an electrical problem in the garage that a handyman couldn't figure out. Great communication, very friendly and professional. Described the cost prior to coming out. Was patient in looking for the problem. Found the problem (it was a faulty outdoor plug that knocked out the garage door openers). Fixed the problem and replaced another outdoor plug. Great experience-highly recommend."

Electrical FAQs, answered by experts

If there isn’t a C-wire on your thermostat, you can repurpose the G-wire. The G-wire controls the fan independently of the other controls on your thermostat, so the fan-only function won’t work if you decide to go this route.

If you encounter any issues or feel unsure about your abilities, stop immediately and contact a licensed electrician for help. It's better to be safe than sorry when it comes to electrical work, as mistakes during the wiring process can be hazardous to your home and personal safety.

Outlets with only two slots have no ground connection. That’s more common on very old outlets, which means it’s more likely the outlet won’t be polarized. You’ll have to closely examine the slots to see if there’s a size difference indicating polarization. Keep in mind outlets this old are usually out of code and should be replaced if you’re doing any electrical work.

A 60W LED bulb is likely labeled as “60W replacement” on the package—that’s because it provides about the same light output as a 60W incandescent bulb. In reality, it likely uses less energy—usually 15 watts or less. If that’s the case, then it’s perfectly fine to put a 60W LED bulb in a 40W socket. Your best bet is to read the package carefully. It will tell you the LED bulb’s actual wattage, and as long as it’s lower than the fixture, the bulb will be safe to use.

The number of outlets and lights you can safely run on a single circuit depends on the circuit's amperage and local electrical codes. A general rule is to allow one outlet or light fixture per 1.5 amps, keeping the total load under 80% of the circuit breaker's capacity. For example, a 15-amp circuit can typically support up to eight outlets or lights, while a 20-amp circuit can accommodate up to ten. Always consider the combined power usage of all connected devices and fixtures to prevent overloading. For specific guidelines and to ensure safety, it is best to consult local electrical codes or a licensed electrician.
