"We have hired Plesh Electric to install a fixed generator. Plesh Electric called us to set up an appt the same day we were on Home Advisor. They came the next day to do a property survey and we received a proposal the very next day. They have not started the work yet BUT I can say that I am very impressed with Lisa their office manager. Customer Service is rare these days and so far in this process she has quickly applied for permits and submitted application to PSE&G. She has kept me up to date and I very much appreciate it. I am looking forward to their guys doing a quality job. Stay tuned!"

"Ken and his team from Transform Electric were terrific! Ken immediately contacted me and was able to come and give me an estimate right away. We started the project a few days later. I had four rooms that needed new recessed lighting installed. The team came on time and started working. They were very professional and reliable. They moved all my furniture and covered what was necessary. When it was all done, everything looked great and I was very pleased with the outcome. They also cleaned up after they completed the job. Overall they did a fantastic job and I would definitely recommend them to others!"

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. 

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.
