Moving this thread over from the Audiophile Receptacle Covers one, because it deserves its own topic; those situations where ignorance, rather than gullibility, is the issue.

We have a lot of huge chicken houses in this area, operated by many folks who aren't really swift in the electrical distribution dep't., leading to many dispariging comments within the trade about "chicken house electricians"
So this farmer walks into the supply house years ago, inquires about the price of a single pole 20 amp breaker for his chicken house. Seems that the original one had burnt up. When given the price he then asked "how much is a 30?" and the same price was given. This went on for a while until the gentleman figured out that he could buy a 50/1 breaker for the same price as a single pole 20, so he got bold and bought a whole carton of the buggers, saying he had gotten much more amps for his dollar... My own experience indicates that #12 stranded will carry about 55 amps in free air, but the TW insulation got pretty soft; but as romex, it would melt., guess you call people like the farmer Job Security.
