"Walker Electric did a great job each time I hired them. On separate occasions they installed two ceiling fans, installed an electric outlet, and finally installed a full house generator. I will have them out again when there is need, and recommend their service to family and friends."

"One of my rental homes needed electrical attention before an inspector would agree to come in. It was an emergency situation and Matt was very helpful. I originally called him after hours and was pleasantly surprised that I was able to talk to him. He patiently listed to my situation and came the next day first thing in the morning. He performed the requested work I needed. Then, worked a miracle and managed to bring the inspector the same day. Not only that, but he also called Duke Energy so that they would turn the power on the same day. I was very impressed with how reliable, honest, and prompt Matt was, and all for a very reasonable price. I will definitely call again if I am in need!"

"The install went great. UES showed up on time, used boot covers while in the house and covered our furniture and flooring prior to starting their work. After the recessed cans were installed, they cleaned up the work area. The electricians were knowledgeable and curteous. They did an amazing job and we are very pleased with their work. The additional lights made a night and day difference in our living room. I would highly recommend UES for your home lighting improvement projects as well."

Generator Install questions, 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. 

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.

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.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.
