question on generator grounding:

Some of the panel makers make them. Square D makes them for their Q0
panels and I think they now have them for their Homeline panels. Others
also have them.

Google "generator interlock kit" or see http://www.interlockkit.com/

Thanks!

It looks like it can be an interesting "home-made" project:

1) Make a template out of cardboard

2) Use the cardboard template to fabricate a working interlock from
1/8" aluminum plate.
