"Had Gridwise install a transfer switch and inlet box for our portable generator. We lose power a few times a year during wind events and got tired of running extension cords everywhere. Michael handled the install and walked us through exactly how to connect and start the generator when the power goes out. He was patient with all my questions. Permit was pulled and inspection passed first try."

"Just got a hot tub delivered and needed the electrical run to it. Mark and crew came out and installed a 50-amp GFCI breaker and ran conduit along the side of the house to a disconnect near the tub. Looked way cleaner than I expected. Passed inspection and we were soaking that weekend."

"I had 2 ceiling fan/lights installed in the bedrooms. Installation included 2 new circular circuit boxes in each bedroom ceiling. In addition, I replaced the kitchen ceiling light with an LED fixture. The 2 workers were very polite and professional and worked quickly and efficiently, in addition to being respectful of my personal belongings."

Generator Install questions, answered by experts

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.

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.
