"i recently had a tesla charger installed, and i am extremely satisfied with the service. the electrician did an outstanding job he was professional, knowledgeable, and completed the installation much faster than i expected while maintaining excellent quality. the work was clean, efficient, and everything was installed perfectly. on top of that, his pricing was very reasonable compared to other estimates i received. it’s not often you find someone who delivers great workmanship, works efficiently, and offers affordable rates. i highly recommend him to anyone needing electrical work or an ev charger installation."

"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

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

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. 

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.
