"LJ did a great job upgrading my panel. The price as fair and he his work was very clean. I really felt like he knew exactly what he was doing and explained it to me clearly. Our panel has been installed for a while now and we have not had a single issue. I would definitely hire him again and have already recommended him to all my neighbors."

"If you need electrical work done, please call J. N. Green Electrical. We started off by calling several companies out to our house to fix what we thought was a minor electrical problem. After three different electricians came out and three different bills, with nothing fixed, we found J.N. Green Electrical on Angie List. We were skeptical at first but said, Let give it a try. Green Electrical was out at our house that same day and was able to fix the problem in no time. They were very professional and charged me less than the other three companies that did not fix the problem. I would definitely recommend them to anyone! They have been our go-to guys ever since!"

"Scott was on time and very professional. He examined the current installation of the toilets and provided me with options to address the problem and install new toilets. I enjoyed meeting him and appreciated his expert opinions. I am still getting estimates and will certainly keep this company at the top of my list. Scott is very easy to communicate with and will brighten your day with his smile."

Generator Install questions, answered by experts

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

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.

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.

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.
