"Brian was awesome and fast and courteous. Princeton Electrical was easy to communicate and negotiate with, and offers a fair price for their labor. Had a Level 2 EV charger installed from my townhouse basement to my garage in a few hours without problems."

"Nick Murray, one of the Murray brothers, replaced a circuit breakers panel in the basement and installed a full house generator with switch panel on my house. Nick did a great job! Very professional and courteous. I would definitely recommend this company for electric works."

"We had a top experience with Star Bright Electric and would highly recommend them. From start to finish, they were professional, polite, and easy to work with. They communicated clearly, showed up prepared, and took the time to clarify any questions before moving forward with the work. The job was completed efficiently and everything was done well. We appreciated that they were respectful of the home, careful with the details, and made sure the work was completed properly. It can be hard to find contractors who are both skilled and pleasant to work with, but Star Bright Electric checked all the boxes. Overall, we were very happy with the experience and plan to use them again for any future electrical work."

"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

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.
