"Current Electric helped us tremendously with our Electrical Box upgrade. We first wanted our power line to be placed underground and Current Electric helped us with the logistics with contacting the electric company. Second, when it was time for the installation to happen, the technicians came on time, worked diligently, and cleaned up after the project was completed. I would hire them for any of our future projects."

"Elliott does great work for a great price. He installed a new 100 amp breaker box and updated some of the house wiring to accommodate the new service. He also wired the newly renovated basement with all the wiring and installed all the outlets, switches and drop ceiling LED lights that have dimmer capability. He is meticulous in what he does."

"He showed up in a timely manner. He did the job quickly. There was a shorted wire that he had to re-run and pull through the existing pipe. So far it's all working great and has not needed to return. So far everything working great."

"We were very pleased with the caulking and painting work Alex recently did for us. The caulking work was near perfect, and the thorough prep work before painting was notable. He went out of his way to guarantee our satisfaction with our painting project. We have no reservations recommending Alex and would hire him again."

"Matthew did a fantastic job installing our new quad-receptacle GFCI outlet in our basement. We will absolutely hire him again in the future!! He was polite, punctual, communicated well with us, and his pricing was very reasonable. He cleaned up after his work, which we appreciated. He's definitely a professional electrician that I would refer to my family and friends."

Generator Install questions, answered by experts

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

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.

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.

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

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.
