"DES installed 2 new electrical outlets, 2 new electrical panels, 3 wall heaters with dedicated circuits, and other miscellaneous electrical work. They explained options and what they would need to do to get the job done correctly. They arrived at the scheduled times, worked around our dog, explained the work they were doing, were friendly and easy to work with, and explained color and size options. When a light malfunctioned, they quickly scheduled an appointment for the waranty work which I am very satisfied with. I would hire them again."

"Three electricians worked on the job & completed it in 3 1/2 hours! I was expecting it to be done in 5-6 hours. They even hooked their generator up to my big freezer! The City inspector just checked their work, said it was a job well done! I would definitely hire them again."

Generator Install questions, answered by experts

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.

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. 

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

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.
