A colleague answers Code questions that range from A to Z. Sometimes he consults with me on some of the unusual questions he is asked. At times they are serious questions, involving complex situations where the Code is not completely clear, other times they are things that are just plain odd. This was todays brain teaser. Why are many of the 15- and 20-ampere, 125-volt cord caps manufactured with a hole in the circuit conductor prongs? I told him I didn't know but was sure I could find the answer here. Hope you guys can help.
