"The RaLo electrician did a great job running new wire to install my outdoor camlight. He also informed me of a number of other issues he noticed and gave me good price to address those issues as well. I definitely recommend their services."

"A+ Top notch service. Installing 1 attic fan, realized needed another one replaced. They went out, got a 2nd one and installed them both, plus gave advice on our under cabinet lights that always blink. Followed up the next day with a $15 solution to try before we do a repair. Good communication - they answer the phone when you call. Showed up on time and done in under 2 hours which included the time to get the 2nd fan."

This generator was installed on the side of a house.  The window had to be replaced to allow for the generator to be placed in this location.  The window was made to not open per code.
We installed this 14kW generator to power the whole house.  We used load shed modules to be able to save the customer money by using a smaller generator than would have been needed if we didn't use the load shed modules.

"Kevin Williams was sent to repair problems created by another electrician hired by Kitchen Saver during an expansive kitchen re-face and cabinet installation. Among other things, he re-located an unsightly transformer that had been previously secured to the inside of the first shelf of a main kitchen cabinet to a lower cabinet out of sight. Voila! Then, he re-routed unsightly wiring previously clamped to the far corner of a glass display cabinet so that it was out of sight. These were difficult puzzles to solve, as the new cabinets had already been installed and there was no longer easy access. Kevin was friendly, professional, and experienced! Great job!"

"William Burden is the third generation owner of WBLightningRods and his company has been in business since 1950. He is very courteous, professional, was on time, and has a very good crew. William was present for the entire installation. We chose the copper system. We are glad for the peace of mind a lightning rod system will provide."

"Great job helping sort out the open neutral I had. I was able to get the new wire, breaker, and outlets installed so the electronics are isolated on their own circuit. Thanks again."

Generator Install questions, answered by experts

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.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

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.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

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.
