"Very good- problem solved but socket in fixture was not possible to be repaired- tech recommended new fixture telling me it was not cost effective to take it down and rewire- we followed his advice. Responsible company- did not charge for a follow up call. Realized it was part of the same problem."

"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."

"Tony came out and gave us 3 estimates for 3 different generators. We chose the Cummins Onan because it suited our needs and provided the quietest operating generator. It also was the highest rated out of the 3. Tony and Marshall dug out a place to set the concrete pad which the generator is placed on.The digging was done neatly. Tony and Marshall then did all the installation of the electrical work. Steve Mays then came and did all the necessary work for the gas lines run and then connected to the generator. Steve worked in our crawlspace running the gas line form the gas meter on the south side of our house to the north side where the generator was located outside nearby our electrical box. Tony and Marshall came back to instruct us in the operation of the generator, which is basically you checking to make sure the green light is always on. Local inspectors gave a green light with the excellent work done. We will need to check the oil ever so often, but that is typically simple. Tony and Marshall and Steve all worked within the timeline which they had given us. They were very professional, caring, neat and extremely well informed about the generator. We had a lot of questions and they answered them all. We called them and they always picked up our calls. We could not have been more pleased with them. If you are looking for a home standby generator, these are the ONLY guys to get!"

Electrical questions, answered by experts

Wire color codes vary depending on the region. For instance, the United Kingdom has updated its wiring codes to match Europe's color system. The United States wiring color code is different, as is Australia's. Because the color code system isn’t universal, it’s essential to hire an experienced electrician to perform any electrical work to ensure it is done correctly.

No, there aren’t additional code requirements for kitchen lights. Kitchen lights and other electrical circuits in the kitchen have different code requirements. Outlets need to be particularly robust because of their frequency of use and proximity to liquids. If you need help determining where to install outlets in your kitchen, consult a local electrician who can ensure that placement is functional and up to code.

A standard three-prong electrical outlet typically lasts for about 15 years with normal use and should be replaced accordingly. GFCI outlets may have a longer lifespan of 15 to 25 years. While some outlets can last longer if used infrequently, they can also fail prematurely. Reasons for early failure include poor wiring, an overloaded circuit, improper grounding or installation, or loose plugs. Signs that an outlet is failing include flickering lights, overheating, a discolored or melted faceplate, plugs that fall out easily, or frequently tripping circuit breakers. It is essential to address faulty outlets promptly to avoid safety hazards, especially in homes older than 15 years.

Poorly designed and incorrectly installed outlets can create an electrical fire hazard, as do some phone chargers and adapters that plug into these outlets. However, most outlets are perfectly safe as long as they remain in working condition. Keep an eye on what you are plugging into the outlet and stay alert for signs of outlet malfunction, like sparks, burning smell, or frequent circuit tripping.

If you find the power cables for your appliances are too short, there are ways to extend them for the cost of just the extra wiring you need. Simply cut and strip your wires, solder them together, and cover them using heat shrink tubing. Not everyone has a soldering tool on hand, so if you’re looking to extend in a pinch, an extension cord, power bar, or surge protector can do the job just fine.
