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

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

Many services include assembling the unit and securing it in the window. Confirm with your provider.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency.
