"Professional, outstanding service & available immediately: Trouble shoot electrical panel fuse trip after lightening storm; identified problem with ground wire between multiple 3-way outlets, made repairs, communicated cause & remedies & made repair. I can’t give NCharge a high enough rating; this is the second successful experience with them after the whole house generator installation. One stop shopping for all your electrical needs, don’t lose their number(!!!)"

Generator Install questions, answered by experts

Many services include assembling the unit and securing it in the window. Confirm with your provider.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.
