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 called and came over right away to give us an assessment of the project and the price for installing a new electrical panel. Fair price, superior work. He was flexible/accommodating to fit our job in quickly since we were going on vacation shortly. The day of the job, Chris stayed till late evening to complete the job. We are completely satisfied. His work is meticulous and neat. Chris is professional, experienced, excellent at his work, and very personable. Would not hesitate to recommend him to all."

"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."

Generator Install questions, answered by experts

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

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.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

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.

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.
