"He is extremely attentive to your needs . What he says will happen , does! He keeps all appointments and thoroughly explains what he plans to do. He is one of the most reliable, ethical , conscience businessman I have ever dealt with. I have recommended him to friends . He actually went out of his way to help Ill friends deal with their generator problems even though he had not installed it. He made arrangements for someone to fix the generator when he was not able. Highly recommended !"

"Tylor was quick to respond to my inquiry and very accommodating to fix my problem as soon as he could. His expertise was shown as he diagnosed the possible issue over the phone and he had it fixed in no time once he arrived. He even fixed a lesser issue for no extra charge. I found his rates exceptional, and he will always be my first call for any of my future electrical issues."

"This was the second job I hired ESC for, the first was a hot tub hookup, and this one wasn't a simple one: install a generator hook up that bypassed only some of my critical circuits to the generator, while leaving the rest of the house on the grid. This required a pretty complex panel with multiple switches and breakers. He did a neat and tidy job and was in and out in about 3 hours! He does the work alone, showed up on time, does a timely, high-quality job and is friendly and considerate to my needs, as a COVID-19 Locked down, WFH customer and he also worked with me on the quote, to get the number where I needed it to be. Kevin *IS* his business, meaning he does the jobs by day and the and invoicing and estimates by night. As he told me: he wants the work but, working on jobs all day doesn't leave much time for getting back to quote request and questions. I think he could do a better job of communicating that up front (why he took a slight ding on my customer service rating) but ultimately I was really glad I waited him out. In short, I'd definitely recommend ESC for your household electrical work, just be patient with his getting back to you. I will likely hire him again."

"Highly recommend!! Peter was very professional and easy to work with. Came when he said he would and finished the job on time. He also returned after the installation was complete to make certain furnace was running well and to install a new CO2 monitor when he noticed mine was outdated."

"I had a small electrical fire on a Saturday from out dated cloth wire. These guys showed up got it fixed to where my house was safe and came back on a Sunday to get it 100 percent done rewiring my out door lights for my front door. Amazing professional work. They came back a little later and re wiring my entire house for me new panel new wires handled the permit. I can’t say enough about their work and professionalism I have no issue leaving them a key to work while I’m not home. Again amazing quality work"

Generator Install FAQs, answered by experts

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.

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. 

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.
