"We highly recommend J.P. McCurdy Electrical Services. We hired this exceptional shop to replace all the old knob and tube wiring (along with switching out a number of light fixtures and installing several ceiling fans) in our 120-year-old Victorian home – a challenging job that a couple of other electricians didn’t feel confident undertaking. Owner Jack McCurdy personally came to size up the job and give us a detailed estimate, and his professionalism, courtesy and extensive knowledge sold us. What was originally thought to be a two-week job was finished in six working days as foreman Joe Costain efficiently deployed his crew and brought in a second crew on a few days to expedite the work. Joe was great at communicating what kind of activity we could expect day-to-day, especially as both my wife and I are working from home fulltime during the COVID pandemic. He and the crew checked in frequently on our preferences, minimized the number of holes in the ceilings and walls (including avoiding harming our wallpaper in a couple of rooms altogether), and cleaned up well at the end of every day. Jack’s estimate was competitive and the final accounting accurately included the additions and subtractions we agreed to during the job. We feel so much better that we’ve finally eliminated the risky knob and tube wiring and updated the entire house’s electrical system. McCurdy is a full-service shop that does all kinds of electrical work – if you want a trustworthy and capable electrician, give Jack a call!"

"I had both electricians and plumbers who performed the work of the generator installation, transfer install as well as the plumbing to the propane tank-generator. Considering the time of year with hurricanes and inclement weather, the generators and transfer switches were backordered however, my job was completed within a 2 month period from the initial quote to finish- considering all of the obstacles that we faced, they did a fantastic job."

"My solar inverter stopped working in my existing solar system, and since my original installer went out of business, I had a hard time finding someone to replace the inverter provided by SolarEdge. It was a small job, and most large companies weren’t interested, while those willing to help were booked out for at least a couple of months. I contacted Justin, and he replaced the inverter within just a few days. He was very friendly, efficient, and offered a very reasonable price. Justin was also extremely knowledgeable, explained everything clearly, and kept me updated throughout the process. He arrived on time, completed the work neatly, and made sure the system was running perfectly before leaving. Overall, his professionalism, honesty, and dedication to customer satisfaction made the whole experience stress-free and smooth."

Generator Install questions, answered by experts

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

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.

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

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.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.
