A bit of a tangent here ...
How often have you seen a panel labled with information besides specific circuit details?
I think we see it all the time .... at a minimum, when certain breakers are marked as the ones to turn on at sunset (outside lights and signs) or to turn off at closing. I've also seen circuits tagged as the ones you want to flip when the Fire Marshal comes to inspect the exit signs and bugeyes. Or, the ones that are also controlled by the Ansul system.
What I'm getting at is that the panel makers have really dropped the ball, by providing products that are so unfit for this most basic of functions. Heck, all they need to do is paint the covers in a satin-white paint that you can write on! Or, for that matter, leave the face of the breaker blank, with a lable to fill in. (Do we really need the UL lable, AIR, etc., to be visible, readable with a magnifying glass, for all time?)
