I got into a discussion about circuits for battery packs and exit signs. Some of my guys questioned the arrangement of circuits and the application of rule 46-400. Is it OK to use a local lighting circuit to supply battery packs and exit signs? The battery packs and exit signs could not be controlled by a switch of course. Maybe a better way to put or pose the question would be " Why shouldn't battery packs and exit signs be fed from a local lighting circuit?". What technical problems could arise from such an installation? Sure could use some expert advise on this one.
Thanks
Bill
