Don't know the details, the sticker is long gone (it had glue similar to that used on old style postage stamps, the ones you had to lick). But I vaguely remember my father saying that you could select your electrical inspecting agency (he worked for an architecture company back then, as an accountant so he knew who could be called upon). But my father checked out about 15 years ago, so I can't ask him about it... I suppose he still needed permits from the town, and someone from the town must have had to check that an inspection had been passed, at some point in time. But that would only require a generic government bureaucrat to do.
