"David G. With The Happy Outlet worked ob a number of electrical problems, repairs, installations and upgrades we had been wanting for almost a year. He worked diligently using his expertise to provide an estimate for each request initially, then beginning to complete each item one after the other professionally. He was friendly and helpful and did not complain about the surrounding chaos . We are in the middle of remodeling the kitchen, replacing the downstairs flooring and remodeling the master bathroom to accomadate handicapped access. Each project was in the throws of demolituon. We also have large dogs who wereantsy with everythung going on around them. Undaunted and calm he met each challenge efficiently without complaint. He is welcome in our house anytime and hopefully will be our swrviceman miving forward for any future electrical needs."

"Jason with Battle Born Electric installed under-cabinet lighting in my kitchen and dimmers on all the many overhead lights in my kitchen and living room. The under-cabinet lighting is also dimmable and, in addition to being practical, really accents that area. Jason was professional, easy to work with and very reasonable in pricing. I am very pleased with the work done by Jason and recommend Battle Birn Electric."

"They showed up on time and did a great job. I made a last-minute change where the charger should be installed, and it was a little further away and harder to get to, but Jacob and his team got right on it made the necessary adjustments and got my charger plug in installed and it looks great. Jacob even took a look at an outlet in my bathroom and quickly fixed that on the way out. The work was top notch at a fair price. I will hire Trouble Shooting Electrical for any future needs I may have."

Generator Install questions, answered by experts

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

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.

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.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

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.
