Frequently Asked Questions

What is a "Transfer Switch," and why is it legally required?

A transfer switch is a permanent device installed next to your electrical panel that safely shifts your home’s power source from the utility grid to the generator. It is technically impossible—and illegal—to simply plug a generator into a standard wall outlet (a dangerous practice known as “backfeeding”). Without a transfer switch, the electricity from your generator could travel back into the utility lines, potentially electrocuting utility workers. Manual transfer switches require you to flip a lever, while Automatic Transfer Switches (ATS) sense a power loss and start the generator and transfer the load within seconds.

How do I determine the correct "KVA" or Wattage for my home?

Generators are sized by their power output, measured in Kilowatts (kW). To size a generator, we distinguish between “Essential Loads” and “Total Loads.” Essential loads include lights, refrigeration, and well pumps, which can often be handled by an 8kW to 12kW unit. However, high-demand appliances like central air conditioners have a high “locked rotor amperage” (LRA), meaning they need a massive surge of power just to start the compressor. For whole-home coverage including AC, a 20kW to 26kW unit is typically required to handle the simultaneous startup of multiple motors.

What is the difference between a Portable and a Standby Generator?

A Portable Generator runs on gasoline or propane, must be manually moved into place, and requires extension cords or a manual transfer sub-panel. They are cost-effective but require manual intervention during a storm. A Standby Generator is permanently installed on a concrete pad, runs on your home’s natural gas or liquid propane supply, and features a self-diagnostic mode where it runs for a few minutes every week to ensure the battery and engine are healthy. Standby units provide a seamless transition, ensuring that food stays frozen and medical equipment stays powered even if you aren’t home to start the unit.
