I went to replace a single pole light switch with a new occupancy sensor switch. 14-2 coming in to the switch and 14-2 going out to the light fixture. Basically the switch was wired in reverse of what you would expect. The two neutrals were on the switch and the hots were capped off together. I can be fairly certain that the neutrals aren't masquerading as hots because I went to the junction box on each side of the romex and all the neutrals and hots are capped off together.
The obvious danger would be going to change out the light bulb with the switch "off" and getting popped.
Any other ramifications for flipping the hot/neutral on a single pole?
(By the way I have rectified the situation. Sometimes peeling back the layers on an old house is like peeling an onion; the deeper you go the more it stinks).
