Gernerator/transfer switch

Can someone help me out here, tia.

When I click on your link I get this:

Sorry, you don’t have access to that topic!

Because you’re a “guest”.

Hi Robert here’s what it says.
Josh don’t forget about the paint contamination. :cowboy_hat_face:

This looked like it was a transfer switch / Breaker in the right panel, am I right? Bottom wire penetration was the plug wire, for the portable generator, that exited outside the house. FWIW, the original panel to the left was a 200-amp for a 2000 square foot house. Majority of the single pole breakers were abandoned/not in use. Kind of screwy … is there something I’m not seeing/ understanding here?
