"Daniel, their electrician has helped us before. He arrived promptly and after discussing with us our issues went directly to work addressing our problem. He successfully completed his work to our satisfaction, discussed the repairs , and was on his way to his next appointment in a very timely manner. We are extremely satisfied with his work in particular and Mr Sparky in general in addressing our needs. Reliability and competence seem to be their hallmark."

"I can not say enough good things about Mr. Kirby and his company. He was very thorough, efficient and professional. I recently hired him to wire my new barn for lights and power as well as some improvements to my new home. We discussed my wishes prior to starting and his knowledge was pivotal in guiding me through the planning and supply process. He knew and adhered to all the electrical codes and he knew his business and trade. He worked very hard and was there every day until the project was complete. He even found some issues regarding previous work I'd had done and helped me resolve those in addition to the project I hired him for. I highly recommend him for ANY electrical project or problem you may have. I will always call him first for any of my future electrical needs."

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.

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.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

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.

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.
