Table from the Square D catalog for QO breakers shows a very limited number of breakers/wire sizes that can be double lugged.

I've used these taps before as well, but never felt it was an optimum solution, as it leaves quite a bit of uninsulated metal in close contact with the adjacent pole ( on a 2 pole breaker) I was also under the impression that some breakers were rated for 2 wires, such as Square D QO,and QOU breakers. My question is this: are any breakers actually rated for 2 wires, and if so any that are used in the solar industry? I know that stud type breakers (like Outbacks) can have multiple lugs on the same stud, or use a double barrel lug. Thanks for your help, Ray Walters _______________________________________________ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Options & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org
