Standby generator
A standby generator is a permanently installed, fuel-powered generator that starts automatically when utility power is lost.
Why it matters
It provides whole-house backup without intervention, keeping critical systems like HVAC, sump pumps, and refrigerators running during extended outages.
Where people get this wrong
A standby generator is not a portable generator. It runs on natural gas or propane, starts itself, and is sized to handle your home's critical loads.
Real-world example
A 22kW standby generator sits on a concrete pad beside the house. When the power goes out, it starts within 10 seconds and powers the entire house.
Where this hits your build
This matters during rough-in and before drywall. Once walls close, adding or moving wiring becomes expensive. Plan ahead.
Most people do not just struggle with terms. They struggle with the decisions tied to them.
