[RE-wrenches] Inverter bypass

[Ray Walters]

I probably still have one of the old QO boxes on the shelf, but I never 
liked them.  Single pole, very tight, and you had to double lug or use a 
weird split bolt arrangement with exposed copper out past the breaker.

I started using these 60A T switches from Northern:

Midnite makes small 30A and 60A T switches as well:
