"Supreme Electric was great. They showed up on time, worked quickly and swapped out the cheap plastic electric boxes and installed the ceiling fans we provided all while cleaning up and leaving no trace. I've had bad experiences before, but this was far different. We are very happy that such a small job was done promptly and done well. That can be hard to find these days. We will definitely hire again as we still need a few things done."

"I highly recommend CAP Electrical for all of your electrical needs! Not only do they do an outstanding job, but they are extremely friendly, customer service oriented, and honest. The day that Rod (President) came out to give me an estimate, I thought that I had a short in one of my kitchen light fixtures. Rod quickly pointed out that I was not using the right type of bulb in the fixture (non-dimmable bulb on a dimmable light). That display of honesty led to me hiring Rod and his guys for the rest of the work I needed done, and I'm very glad I did. They ended up installing recessed lights in my basement, a receptacle on my front porch, repairing switches in my main breaker panel, and fixed existing receptacles throughout my house. The electricians Rod sent were very personable and courteous. They worked very efficiently, and ensured that my satisfaction was their number one priority. As the electricians worked they informed me that some of the work that they did was not as involved as originally anticipated, which ultimately led to me saving money. Another display of honesty and customer service at its finest. In addition, CAP was very flexible when it came to scheduling a day to come out. If you're looking for a company that prioritizes customer service and is extremely honest then look no further than CAP electrical. They are very good people who work hard and do the right thing! I'm very pleased with the work that they did and I know you will be too."

Generator Install questions, answered by experts

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.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

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.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

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