"This afternoon Trevor came to my house to repair an outlet. He was knowledgeable, and explained how he would proceed with the repair. He worked quickly and efficiently, and it should be noted he cleaned up upon completion. I would highly recommend Princeton Electrical in the future. Trevor was excellent."

"The quality of work was poor, some of switches do not work, some of the electric outlet did not work. I contacted the service provider but never heard back from them. The service provider did the bare minimum to complete the job. The quality of the hardware installed is as bad as it can be. It would have been nice if he gave us a few options, showed us what he was going to install but he did not. We got what he chose for us.

"I HIGHLY RECOMMEND Drilon and Barry from B&D Electrical Construction because of their excellent service, knowledge, honesty, professionalism and kindness. My home was without power, due to damage in the exterior wire and rust in the wire pipe. Drilon and Barry provided high-quality service to install new exterior wire and durable PVC pipe during almost freezing conditions today! I am extremely grateful because Drilon and Barry realized the urgency of my situation and decided to postpone work on a current project, in order to restore electricity to my home for a Happy New Year. Indeed, I will be having a Happy New Year because I will have electricity and heat in my home! Drilon and Barry expertly diagnosed the problem with my electricity and provided me with an organized work plan and a reasonable estimate of the costs. On the day of our appointment, Drilon and Barry took time to drive to a 2nd store because the 1st store did not have all of the necessary supplies for the project involving my home. Drilon and Barry also went beyond their scope of work and were kind enough to plug the minor holes created by the screws from the previous exterior wire pipe, as well as address the potential hazard of a live interior electrical wire with exposed and frayed copper filaments. I admit that I was very curious about electricity and electrical work. So, I asked a plethora of questions. I genuinely appreciate the patience exhibited by Drilon and Barry to answer my questions about the details of the electrical repair, as well as my questions about voltage, amperage, grounding, 110 volt vs. 220 volt service panels, dedicated service lines and insulation of exterior wires. I was very impressed by Drilon and Barry. As such, I have made arrangements with Drilon and Barry to undertake a 2nd project in the beginning of 2017 to update the interior electrical wiring and install a dedicated service line in my home. Also, I plan to refer Drilon and Barry to my colleagues- GREAT JOB! Sincerely, Wil Lo, MD"

Generator Install questions, answered by experts

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.
