If we were being honest we would say "holiday lighting" is the unwritten 90.2(B)(6).
We just seem to hold our nose, sing Jingle Bells and hope these folks take down the lights before the house burns down.
345 days a year we go around insisting on bubble covers, wet location wiring methods, GFCIs and examining equipment for it's suitability for use in wet locations. We try to insure work is done by qualified installers.
Then sometime in December we pinch out nose tight and watch all sorts of total crap being sold and installed by people who have no electrical knowledge and no idea what the hazards they create could do.
