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:

Kris, It was SqD QO403, and it was a 3-pole load center/disconnect,
not 4-pole. You may recall that the dual-inverter Trace Power Panels
of long ago used two of these, each one serving as an inverter bypass
switch to one 120V AC leg.

Hi All,
I have a stand alone system that was upgraded from an FX inverter to
a Radian WITHOUT the companion load center. I would like to add an
inverter bypass circuit to operate the house on generator power.
There used to be a 4 slot breaker panel (SqD?) with the rocker switch
preventing both breakers from being in the on position
simultaneously. I have not been able to find it on the interweb.
Anyone know of something out there that would meet my needs?
Kris
