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

In general, 200 amps is enough for a house with a square footage of up to 1,800, or the average three-bedroom home. A 200-amp service allows your home to warm and cool itself while running multiple appliances at once. It's a good option for homes that have been extended, or after adding new appliances. 200-amp service is the current standard for homes, so in most cases, it will work for you.

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.

You will need a permit for any electrical work that involves installing or replacing wiring, moving or installing new fixtures, switches, or outlets, hardwiring appliances or HVAC equipment, installing subpanels, and upgrading electrical service. You typically don’t need a permit to have an electrician replace an existing light fixture or electrical box. You can always call your local building department to see if your project needs a permit, but a professional electrician will be able to tell you. In most cases, your professional will pull the permits for you.

The wrong-sized wire can lead to several safety hazards, including structural fires, surges, power outages from tripped breakers, and electrocution. It’s important to follow the American Wire Gauge system and the National Electrical Code guidelines to safely wire a home. Electrical wiring is not safe for homeowners to handle and is best left to a licensed electrician.

You can install a dimmer switch on almost any light as long as the switch, bulb, wiring, and wattage are compatible. Check what kind of light you have, the type of light bulb, and the total wattage of the bulbs to ensure your dimmer is a match. You’ll want to choose a non-neutral wire dimmer if you don't have neutral wiring. Homes built before 1985 that don't have updated electrical systems may not have neutral wiring.
