The model number you gave is for the cover, you need the model of the panel itself.

Some of the Square D panels say what interlock they use inside the pan.

 

Yep, that's the right one.

My neighborhood keeps losing power so I think I am going to offer a portable generator setup to all my neighbors. All houses are set up the exact same way with the exact same panel.

All interior 200 amp main breaker 30/40 Homeline panels. Would be able to knock one out in less than an hour.

Now all I need to do is find a supplier that sells these for the right price.

 

Yep, that's the right one.

The right what? It listed that interlock inside of the pan?

A long time ago in a galaxy far far away, my boss bought one and brought it to a fab shop and had them make about 50 for the price of one.

 

The only problem I see with this is the panel is mounted with the main breaker on the bottom.

That shouldn't be a big deal should it?

 

The directions on the interlock may read "slide up" and so if the panel's installed with the MB at the bottom this could be a violation IMO.
