"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."

"Tough outdoor location to install a Tesla EV charger, but he got it done with exceptional attention to detail. It looks great. Communication was excellent throughout the process. He proposed multiple installation options."

"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

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. 

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

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.

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.

Costs range from $500 to $2,500, depending on generator type and installation complexity.
