"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."

"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."

"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."

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.

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

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. 

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.
