Nope they are asking about using a box with a 5-15 inlet connector and a SPDT snap switch to switch a 120v line.
The generator is set up as an SDS (neutral bonded)
Single family dwelling if that matters.
They assume most of the loads will be C&P connected. This is for a well pump but I did have the same question asked from someone up in the frozen north who wanted to do the same thing with a (gas) furnace blower.
I suppose if you used a center off snap switch it solves the disconnect problem but is it legally "transfer equipment"
