Customers say: Quality work

"Vinny was an excellent electrician. From start to finish, he was easy to deal with and we had clear communication throughout the entire process. He provided great service at a fair price and did a very good job installing light fixtures, repairing broken outlets, and installing a 40amp outlet so I can charge my electric car. I would recommend him and do business with him again."

"Chris was great, came in and got right to work, was pleasant, let me know what the work would entail, not a penny over quote and significantly less than others in my area. Will definitely use him again if we need electrical work again."

"Ryan is awesome! We needed to upgrade our garage electrical + smoke detectors & pool alarms @ our rental property in L.I. (Permit dept requirements) Ryan arrived right when he said he would & he stayed extra to help ADT solve a new thermostat issue. He texted us pics of each repair/replacement he did before he left the property. He gives good & honest advice, & is very easy to work with! Other electricians we contacted for this last minute project didnâ t even bother to get back to us! I highly recommend RCK Electric."

"All I can say is WOW, what a team! Brooks and Patrick spent the whole day yesterday, in my home, doing electrical upgrades and repairs including: Dusk to Dawn lighting, High Hats, Motion lights, New GFI outlets etc. They worked non-stop, refused multiple offers for food and drink, and completed each job to perfection. It was quite impressive watching them problem solve and rectify any issue they came across with the old wiring. When everything was completed, they walked me around the house making sure I was satisfied with all the work. Very satisfied I am, and highly recommend this team. You're gonna love them!"

Generator Install FAQs, answered by experts

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

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.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

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.
