[RE-wrenches] DC Disconnects on Roof

[Bruce]

Hi all.  It seems that more fire departments are requiring a DC 
disconnect to be placed on the roof.  I'm wondering if anyone is using 
anything other than the Square D heavy duty disconnects for this.  Has 
anyone found a disconnect that can be installed in a non-vertical 
position on the roof?  And finally, is anybody working on a roof-mounted 
disconnect that would be controlled by another disconnect located on the 
ground?

Looking forward to your responses.

Bruce
