"Lowest price among multiple quotes and significantly more attention to detail and the least visible and least intrusive installation of new wiring from the existing panel. Would definitely recommend and use Mark H. Anderson Electrical Services again!"

"From start to finish, Long Electric had our backs. We didn't have to hire sub-contractors or to obtain permits -- Long Electric took care of everything. Our go-to person in the main office, Melissa, answered all of our questions and kept us apprised of everything we needed to know. Everyone we had contact with throughout the installation project treated us with the utmost in professionalism. Not only will I call upon them for future electrical needs, I have referred Long Electric to a friend who is also interested in a whole house generator."

"I had a wonderful experience with Electrical Connections. My project ended up being much larger than I anticipated it would be and they were excellent at explaining everything and helping me understand what needed to be done. Customer service was top notch and clearly a priority for everyone I talked to from the scheduler to the owner of the company. Brian was excellent and stayed until the job was done even though it made an extra long day for him. Highly recommended!"

"We had five different things for Lou to fix, including a chandelier that needed to be lowered and made level. Lou rounded the oval links in the chain that held the chandelier and that made it level for the first time! He figured out why a ceiling fan was making noise and why another one wasn’t working at all. He also replaced part of our electric panel which had somehow gotten water inside and was corroded. We didn’t have the right part to change lights in our Faber stove hood, but Lou did, and quickly replaced them for us. We were really pleased with how knowledgeable and competent our electrician was and plan to call him again if we have any more electrical problems."

"I needed a dedicated 20amp circuit and outside outlet installed to my patio. Maitiai arrived on time, was friendly/professional, and completed the agreed upon work. He filed for the appropriate permit with the City of Frederick, and helped schedule the inspection which passed without issue. I would have no hesitation contracting with him again in the future."

Electrical questions, answered by experts

The purpose of pigtail wiring is to connect multiple wires to a single terminal on a device. Pigtailing involves splicing a short length of wire, called a pigtail, into the multiple wires that need to be connected. The pigtail wire is then connected to the single terminal on the device, allowing all of the wires to be connected at once. This practice helps to simplify the wiring process, reduce clutter, and ensure a secure and reliable electrical connection.

If you’re outlet isn’t working but the breaker isn’t tripped , that could mean a number of things. First, check if it’s a GFCI outlet, which has added protection so your breakers don’t malfunction. If that’s the case, simply hit the outlet's reset button and see if it works. If it doesn’t, or you don’t have a GFCI outlet, you might have a loose outlet or loose wiring, a damaged breaker, or an overloaded circuit, which would require a dedicated breaker. It’s best to consult with an electrician to diagnose the problem accurately.

A light switch can stop working for several reasons. Typical causes include a blown fuse or tripped circuit breaker, both of which shut off power to the switch. Worn-out or faulty internal switch components can also prevent it from functioning properly. Loose or disconnected wiring within the switch or electrical box is another frequent issue. Additionally, switches may fail due to age, excessive use, or physical damage. In some cases, problems with the light fixture or bulb itself might be mistakenly attributed to the switch.

Moving an electrical outlet typically costs between $25 and $300. The final price depends on several factors, including the type of outlet, the condition of your existing wiring, and the state of your walls. For example, working on exposed walls without drywall is easier and less expensive for an electrician. However, if the walls are finished, the cost may increase to account for necessary repairs afterward. It's recommended to consult a professional for a precise quote based on your specific situation.

If your breaker box won’t reset, stay on, trips when overloaded, or gets seriously damaged, you will need to replace the breakers or possibly the entire panel. A damaged breaker can lead to a fire, so it’s best to err on the safe side and look into replacement. Hire a professional electrician to replace a breaker box to ensure your personal and property safety.
