So many safety assumptions are made by the general public (the "handyman", etc.)for instance, an AWG 16 lamp extension cord can safely handle a microwave, a coffee pot and a toaster... simply because there are three receptacles at the end of the cord...
Or... if a breaker or fuse opens when your emglo compressor fires up... put a 30A on it..
Or... LXW boxes can handle 4 #10-3-G NM Cables because there are four holes...
Or... Neutral and ground are the same thing...like a chassis ground on a car, right...?
It never ceases to amaze me the things we run into... And, thank goodness, were discovered before harm was done.
