"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."

"A+ for being prompt, accurate on time and on the scope of work. I did request to install needed equipment to run the generator and my house had some non-standard situations. I love that all challenges were solved in the right way, not the fast way. The electrician was very open-minded for debating on the possible approaches to an unexpected situations, etc. I love the work, very rational pricing and I would hire again."

Generator Install FAQs, answered by experts

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.

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.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.
