I am pretty sure it is in the draft of the 2011 code. While we are not governed yet by the 2011 code, I think it is good practice and is something we should all do sooner than later. Borrego is moving that direction as we speak. No reason to wait around for the code to tell us what we have to do. I would recommend getting an integrated load break combiner - there are several on the market already - and breaking the output circuits from the combiner immediately so that conduits running on the roof and through the building can be de-energized in the event of a fire.

I don't see anything about this in the NEC. Any truth to this? thanks Troy Harvey --------------------- Heliocentric 801-453-9434 [email protected] _______________________________________________ List sponsored by Home Power magazine List Address: [email protected] 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 _______________________________________________ List sponsored by Home Power magazine List Address: [email protected] 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
