"Klaus, owner of Resolute Electric, showed up initially to complete the estimate. Klaus was on time, professional and left us feeling we chose the right guy for the job. Klaus provided an estimate within 24 hours, we scheduled the date of the installation and Klaus arrived exactly when he said he would be there. He was very knowledgeable about what needed to be done, did not hesitate to get started and completed installing the flood light in exactly the area we wanted and removed power to the base board heating at the junction box. The flood light needed to be hard wired and Klaus was nothing less than stellar from the moment we met him to the time he left after completing everything we requested. Resolute's pricing is very fair and anyone that uses Resolute will 100% be satisfied with the price and work performed."

"I converted an attic into a 1 bedroom apartment with private bath, kitchen and laundry area years ago and contracted Brandon Oakley to do all of the electrical work. The job was completed timely, professionally and without any issues. Since then his company, Legendary Services, has expanded its services to now include installing back up generator systems and solar systems for sustaining your electrical needs during power outages. I have discussed these options with him and he is very knowledgeable and I am considering installing one or both of these systems in my home. I trust his judgement and his work based on great past experience."

Generator Install questions, answered by experts

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.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

Many services include assembling the unit and securing it in the window. Confirm with your provider.
