"Everything about Able Electrical Services service was superb! I was in a jam, and Able Electrical Services came to the rescue. Both of the mechanics that assisted were excellent. Russell Ridgway was the primary mechanic and he was amazing! His work is superior and he exceeded my expectations every step of the way. For example, I needed electrical outlets to connect install a wet bar. He measured the wet bar and installed the outlets exactly where they were needed and ensured sufficient power was added to accommodate a kegerator and mini-frigs. I highly recommend Able Electrical Services and hope I never need to use any other electrician."

"I hired K & K to install a range hood. There was no electrical there previously so they had to run electric. I also had them install a new light fixture and remove an exhaust fan. K & K did excellent work and even repaired an electrical box that another contractor had installed. I was given a great estimate and was charged the estimate price. Would definitely use again and recommend."

"The generator didn't function for a while. It turned out to be an internal connection issue. They were difficult to deal with regarding this problem. They just walked away after the install and the subsequent visits. This went on for a month. They'd come back out, get it working, and it would fail. They also sold us a cold weather kit that I didn't anticipate buying, and they said that this kit was causing the issue. Finally, a tech took the entire morning to resolve our issue. He found that there was a wire not plugged in. After he plugged it in, everything was fine."

We had nothing short of a great experience beginning with the initial estimate to the install. Install was quick, efficient and CLEAN. We 100% will be hiring Alex again for future jobs! If you're looking for a reliable, trustworthy electrician, Alex is your guy!"

"Eddie and his team did a phenomenal job installing the Tesla EV charger and a sub panel. I had some additional requirements for monitoring the power load to the charger which he researched into and took care. His price was very reasonable and the installation process was very smooth and efficient and he took care of the county inspection/ permit process without any issues. Highly recommended!!"

"I selected Mr. Jefferson after talking with two other vendors. He arrived timely, worked quickly and competently, and provide good advice about the products which he installed. His price was competitive, and her recommended someone for another service that I needed. I will probably use him for future electrical projects."

Generator Install questions, answered by experts

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.
