Customers say: Quality work

"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

Most ceiling light fixtures only have a black, white, and green wire, but in some cases, you’ll also find a red wire in the box. This is a second hot wire, like the black wire, and is included for ceiling light kits that have a fan.

Appliances in your home that need dedicated circuits include:

  • Refrigerators and chest freezers

  • Electric ranges, microwaves, and toaster ovens

  • Dishwashers and garbage disposals

  • Washers and dryers

  • Heating and air conditioning units

  • Hot tubs, saunas, and water pumps

  • Sump pumps

  • Central vacuums

When removing an old security alarm system, you likely won't need to remove any of the wiring. Wiring can either be left in place for a replacement system or capped off for safety and pushed into the wall. If you're uncomfortable with the wiring, or if it's badly damaged, contact a professional electrician for assistance with safe removal.

Yes, placing an electrical panel in a bedroom is perfectly acceptable, so long as it meets other space requirements as indicated by OSHA and related agencies. When installed in a bedroom, electricians typically place it in the area directly behind the door swing. This method allows for easy access when conducting electrical panel repairs.

When wiring a switch, the power typically comes into the receptacle first. The neutral wire goes straight to the outlet, while the hot wire is split. You'll need a wire nut to splice the hot wire back to one of the receptacles, but you will also tie another wire into that same wire nut and run to the switch. That way, you can control the flow of electricity to that particular receptacle by turning the switch on and off.
