"I live in a 128 year old home. It required a new and larger circuit box, some re wiring from the street to the house, larger conduits. I also wanted some puck lights in a new walk in closet, office and hallway with NO previous lighting or wiring. Randall didn’t not back down from this challenge. On time, on point and extemelt hard working man. The circuits have never blown since the new install, the lights are amazing. He even indulged me in hanging and wiring a new 6’ diameter fan/light combo in my living room. When I tell you THIS IS the only electrician you need. I am not wrong. Thanks so much!"

"The two electricians came in and began searching the fuse box and finally found the switch that wasn't working. They also performed a checkup on my electric system at my request. They did a very good job and I do recommend them for anyone who needs the help."

"We received a home security system & Ring door bell from our Kids for Christmas. Unfortunately, we didnâ t have a convenient or inconspicuous place for the modem and needed the Ring installed as well. We know nothing about electric, so I called CCEC and spoke to Patrick. He was very professional and friendly, he made me feel at ease about putting a new outlet in the wall and promised it would be tidy and behind the tv. â You wont be able to see itâ Iâ m a bit of a neat freak so this was important to me. I was so at ease with him that I also asked him to install a dimmer switch in our kitchen, again something Iâ ve always wanted but had no clue or time to do it. On appointment day Patrick showed up on time and ready to go! Jobs were done in a timely matter and the rooms looked just as they did before he started. Patricks work was very professional and so reasonably priced we asked him to come back and install a new pool light. He has done that now too, And again, great service, great pricing, as well as excellent communication (Iâ m technically challenged, he very patiently showed me how to change the colors from my phone as well as manually!) I would highly recommend CCEC, Patricks work is amazing! Patrick, Iâ m already working on a new list and will be calling you soon!!! Thank you for jobs well done!!!!"

Generator Install questions, answered by experts

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

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.

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.

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.
