Manual transfer switch
A manual transfer switch requires someone to physically flip circuits from utility power to generator power during an outage.
Why it matters
It costs less than an automatic switch but only works if someone is home to operate it.
Where people get this wrong
A manual transfer switch is not the same as plugging appliances into a generator with extension cords. It is a proper, code-compliant connection to the panel.
Real-world example
The power goes out. You walk to the panel, start the portable generator, and flip the manual transfer switch to route power to your selected circuits.
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.
