"Very responsive, extremely knowledgeable, excellent problem solvers. They kind of really solved the mystery of why the generator didn't work that had to do with the electric."

"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!"

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."

Electrical questions, answered by experts

Yes, you can connect two extra outlets (or more) to one outlet if the total load on the circuit allows for it. If you have a 15-amp circuit, electrical code allows up to eight outlets or light switches. But if you’re dealing with outlets in the kitchen and bathroom, you may not be able to have as many. Kitchen and bathroom appliances often need higher amperage. You can also change a single outlet to a double outlet by cutting a larger hole in the drywall and replacing the outlet with a quad receptacle.

You can identify Federal Pacific Stab-Lok® breakers by the label on the front of the panel that says “Federal Pacific” or “FPE” and the breaker itself should say “Stab-Lok®” either on the face of the panel or a label inside the panel door. The Stab-Lok® breakers are also usually red on the breaker switch.

This type of conversion is easy—you’ll just need to upgrade to the correct amperage in your wires before wiring the new outlet. However, these projects can be tricky without intermediate electrical knowledge, so consider consulting a pro before flipping any switches on your circuit breaker.

You should never wire neutral and ground wires together at a light switch. Not only is it unsafe, but it’s also incorrect. The neutral and ground wires perform separate functions in an electrical circuit and should never be swapped or wired together at a light switch, light, or outlet. 

There are three main wires on a doorbell, typically color-coded white, black, and green, that are connected to a transformer box in your home. One wire runs to the doorbell button, another wire runs to the door chime, and the third wire runs between the doorbell button and the door chime.
