inlet and switch for boiler

[g-and-h_electric]

I have a customer that wanted a "pigtail" for his boiler so that in case of power outage he can connect it to a generator.

I know that it is a code violation and a UL violation to do that. Can I use an inlet ( nema5-15), and a DPDT wallbox toggle switch to achieve what he wants, and still be code and UL compliant? IMHO, the switch will give me isolation to prevent a backfeed, and the inlet keeps the boiler hardwired.

Am I correct, or at least close?

You don't even need a DPDT, you don't need to switch the neutral. A motor rated SPDT will be fine.

Reliance makes a single circuit transfer switch just for this purpose. Includes a CB. Reasonably priced.

They also have a version with a 5-15 inlet in box. Several other companies make similar, of varying quality.
