"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."

"Joe contacted me same day of my request and visited within a day or two to provide a quote. Everything was done as he explained (and I don't know much about electricity) and on time. When the work was finished, my service line was up to standard and we tested the generator install, all done perfectly."

"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!"

"Expensive but professional. The electrician that did the work was excellent and seemed.to enjoy explaining what he was doing and why it had to be done that way. I felt like I learned something while he installed ceiling lights. He also cleaned up after himself like he'd never been there."

Generator Install questions, answered by experts

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

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.

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.

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. 

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.
