"Mike Connelly of Shamrock Electric Co. Coordinated the installation of my whole house Generac generator with PSEG long island and my plumber. He connected the automatic transfer switch and fully tested the system upon completion of the install. He has it set to run a test for 10 minutes once a week. My wife and I are extremely happy with the unit and the professional set-up by Shamrock Electric Company ."

"From start to finish, Best Quality Electric delivered an exceptional, white-glove experience. The process began with a dedicated consultation that was educational, detailed, and thoughtfully planned—setting a clear vision before any work even began. The following day, the team arrived precisely on time and immediately demonstrated a level of professionalism that is rare to find. Shoe protection was used, and every floor and piece of furniture was carefully covered. Their respect for the home was as impressive as their craftsmanship. Watching the two electricians work was remarkable. They operated in perfect sequence, anticipating each other’s next step, covering every single detail with precision. Not one question went unanswered—each was met with patience, clarity, and deep expertise that inspired complete confidence. Best Quality Electric truly lives up to its name. This is not just electrical work—it’s a refined, high-standard service experience. Bold, meticulous Toptier work!"

Electrical questions, answered by experts

The most common reason a GFCI outlet would trip even when nothing is plugged in is if there’s a problem at the circuit breaker end. This could be an overloaded circuit, with too many appliances plugged into it, or another type of fault. If a GFCI outlet keeps tripping, it can also be because it is faulty and needs replacing.

Multiple wire sizes are used for residential electrical purposes. While the most common sizes used in homes are 14 and 12 gauge, some appliances, such as stoves, electric water heaters, central air units, etc., may use larger gauge wire to accommodate their larger amperage. Typically, larger appliances require 10-, 8-, or 6-gauge wires.

The National Fire Protection Association reports that almost half of reported electrical fires are caused by electrical distribution and lighting equipment. The main culprit behind these fires is often frayed, worn, or faulty wiring, particularly in closed-off and concealed areas like attics, where fires can start and burn undetected for long periods.

The common, marked as COM or C, is one of the terminals found in your light switch. It houses the live wire that supplies the input voltage. The other terminals, marked as L1 or L2, are the outputs to the light fixtures. Depending on if you have a one-way or two-way switch, you’ll either have just an L1 terminal or both an L1 and L2 terminal.

Yes, electricians must be licensed, certified, and in most cases, insured. Licensing requirements vary by state and local municipality, but most U.S. municipalities require electricians to hold an electrical contractor’s license. It's always a good practice to confirm requirements with your local municipality. Even if licensing is not required in your area, hiring a licensed and experienced electrician often leads to a better end result.

A license is a legal requirement to operate a business and is necessary for pulling project permits. Certifications, on the other hand, are typically voluntary and demonstrate a certain level of expertise. In some cases, a certified electrician may send an apprentice or journeyman to perform the work, but they must operate under a primary electrician who holds the proper license.

Before hiring, you should verify the electrician's license, insurance coverage, and any third-party certifications. You can use Angi’s contractor licensing search to confirm a pro's license status. Additionally, businesses with the “Angi Approved” badge on our platform meet strict criteria, including having the required state and local licenses, passing a background check, and maintaining a high average rating.
