"Great experience with BriteBox Electrical Services. Cory Henderson was professional, respectful, and easy to communicate with from start to finish. I showed him where I wanted the outlet installed, and he handled everything with precision. He took the time to protect the work area, safely shut down the circuit, and completed a clean, high-quality installation. The workmanship was excellent. I’ll definitely be requesting Cory again for future projects. Highly recommend!"

"Very professional and courteous. I was able to obtain a same day service appointment, which I really appreciated because I work from home and every time I printed something, my eelectricity on one side of my house would go out. The technician also upgraded my hall wall units with night lights. A very special touch that made my hallways bright at night and elegant!! I would definitely use them again."

"Joe is an honest and hardworking individual who does high quality work. He was there when he said he would be, answered all my questions and did an excellent job running power to my new gate, wired up the lights and openers, and even had to do some extra work (at no charge) due to an unforeseen problem not of his making. I would not hesitate to recommend FC Electric and will be using them again in the future."

Generator Install FAQs, answered by experts

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

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.

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.
