"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!"

"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 FAQs, answered by experts

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. 

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

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

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.
