We offer the best quality electrical work, we strive into quality work. Very responsible on our schedule. We offer a clean environment, leave the project cleaned and strive on making the project go smooth as possible and avoid hassles and drama for homeowners.

"In May 2024, we embarked on an ambitious project in southwest Michigan, but ran into a significant setback when our original local contractor failed to show up and abandoned the job for over two months. Fortunately, we were referred to D-Best Electric by another contractor, and it turned out to be one of the best decisions we could have made. From the moment Oscar and his talented team took over, we experienced a remarkable turnaround. They not only completed the project within the agreed timeline, but their expertise and attention to detail were truly impressive. The crews were exceptionally knowledgeable, demonstrating a high level of professionalism and skill in every aspect of their work. What truly stood out was how D-Best Electric went above and beyond by addressing numerous additional requests and adjustments without any hesitation. Their commitment to customer satisfaction and excellence made a significant difference in the overall experience. Given our outstanding experience, we will undoubtedly rely on D-Best Electric for all our future projects. I wholeheartedly recommend them for any residential or commercial electrical work—trust me, you won’t be disappointed!"

Generator Install questions, answered by experts

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.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

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.

Yes, whole-house generators run constantly for extended periods. Whole-house generators can run for longer periods of time than portable generators, but be careful. First, they may need regular applications of engine oil (as frequently as daily), depending on the engine design. Second, running constantly for several days will increase the wear and tear on the generator and shorten its lifespan.

By submitting this question, I acknowledge and agree that Angi may publicly display my name, city, state, and question on the website for professionals and others to see.
