"Mr. Orr quoted installing 30-amp generator inlet box for $1,000 and 50-amp for $1,300. I agreed on 50-amp one. He did not want to be paid by personal check, credit card, even bank cashiers check. He accepted only cash. I agreed. For permit, he said his hourly rate is $250 and two visits to town office would cost additional $500 for permit and stated I do not really need it. Considering he is in Angis list licensed, prescreened, I accepted the offer without permit. He installed the service. No receipts, no insurance information, and with my acceptance, no permit. He did not even try my new generator after installation to see if everything works fine. It was partly my mistake, though. I feel humiliated now. No one should work on panel without town permit. I had to call another electrician after the work. The cable from inlet to panel was 8-3, not 6-3 gauge for 50-amp inlet. I called Mr. Orr and requested a proper gauge cable or reimburse me $300 for the lower grade work. He did not want to come, saying it is a 45-minute distance. He agreed to send me $100 by his personal check, saying I would not have any problem with my generator's output (The Westinghouse WGen9500DFc Dual Fuel Portable Generator with CO Sensor produces up to 12,500 peak watts and 9,500 running watts), dividing 9500 watts by 240 volts. He said I do no;t even have 50-amp output anyway and I should not worry about it. Now, another electrical contractor who replaced the panel to 200 amp, replaced the 8 gauge to 6 gauge, as well."

"Jason and his team with Cotti-Johnson did an excellent job updating our electrical boxes, installing the washer/dryer hookup, and getting us setup with a generator! Sam, our assigned electrician, even took the time to go through the entire operation of the generator from A-Z. I would definitely recommend them for any electrical work!"

Generator Install questions, answered by experts

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

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 standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.
