"Scott is excellent to work with in all aspects of electrical. I am a general contractor and Moses Electric has done all my electrical for the past 12yrs. I look to no one else. From the non working outlet or switch, to service upgrades, underground work, data, fire alarm panels, low voltage, new construction, remodeling, troubleshooting, all the way to 3 phase industrial and commercial work. Scott has been along side me for all aspects of the electrical work and never skipped a beat. I have full confidence to refer Moses Electric to my own clients, friends and family. Knowing when I pass his name along it will not come back to me with a negative effect. Always happy clients every time, in addition to being clean in all aspects of presentation and workmanship. I am not biased because I am in the trades. We rely on referrals and relationships to provide our living so there is no benefit to saying what isn't true. I highly recommend Scott and Moses Electric for any of your electrical needs. He makes the process easy and seamless."

Generator Install questions, answered by experts

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

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. 

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

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.
