"I can t recommend Markus highly enough. Once contacted, he was prompt to respond and provided a written formal quote, which included cost breakdown of all materials and labor. He upgraded lighting and other electrical associated with our full kitchen remodel. The materials he recommended and installation fit our needs perfectly. The job was performed in 2 phases, before drywall and after drywall/texture/paint. Each time the workspace was left clean and free of work debris. He is courteous and able/willing to make changes on the fly. A true professional."

"We had a very old heater in our mobile home that finally died. Called Wighton's and Patrick came out and gave us lots of information and a quote on a new unit. He was very personable and helpful. We then had Ivan install our unit. He was very professional, polite, and informative. From beginning to end, this was a very positive experience. Even felt the price was good!"

"The job was done quickly. The plumber installed a new garbage disposal, fixed the sink faucet issue another plumber said was unfixable, and repaired a toilet. He was polite, efficient and cleaned up after himself thoroughly."

"I echo the thoughts of so many others and that of Sydney, in that you would think Link Electric wrote this review. Marcus is incredibly polite, attentive, easy-going, upbeat demeanor, professional and most of all, knowledgeable. When he told me he had finished installing the outside breakers, I was taken back because it he did it so quickly. I have another project to be done and Marcus will be the person I hire! He is truly exceptional like so many other have written."

Generator Install questions, answered by experts

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

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 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. 

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 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.
