Emergency Light Test Switch.

Zoomup
Is it o.k. to use a non switched fused connection unit as an emergency light test switch? If not why not?

    With those FCUs with a fuse draw that slowly comes out as the holding screw is turned, I wouldn't like to use it as a functional switch with any significant load - certainly not regularly - at some point in the process there'll be just a slight gap between the fuse and contacts and it'll arc - doing the FCU no good at all.

    No fuse drawer worm screw involved here Andy, just a flat bladed screwdriver.
