"I am very pleased with the service I received from Mr. Electric of Gastonia. Daniel and Matt explained all the issues with the old panel and I decided to have it replaced along with a whole house serge protector. While they were here they kept me informed of what they were doing and how the job was progressing and when they were done they cleaned up. Daniel and Matt were always on time and they called ahead when they were on their way. Brian set up my appointment times and scheduled me for the electrical inspection so I didn't have to do any of that. The inspector was here this morning and told me that it was really nice to see good quality electrical work. I would not hesitate to refer them to family and friends, I am happy with the job they did for me."

"Drew, the owner of Walker Electric was the technician that actually showed up to do the work. I had him install a ceiling exhaust fan in my bathroom. He did excellent work replacing the old one with new and didn’t do any unnecessary drywall damage. I also had Drew install under cabinet strip lighting in my kitchen that came out looking wonderful. His pricing was more than reasonable and his quality of work was top notch. I would recommend Walker Electric for any of your electrical needs and I will absolutely be using them again in the future!"

Generator Install questions, answered by experts

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

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.

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.
