Why do some people remove the third part of a 3 wire AC power cord?

This action was done in the past but not so much now. It was a case of the manufacturer installing a grounding pin in their cords while homes were still using two blade receptacles. Prior to new homes having to install a grounding receptacle, homes were wired with only two slot receptacles. These two slot receptacles just had a "hot" and neutral connection for 120 volt output supply and no accommodation for the grounding of the receptacle. The new three pin extension cords would not fit into the two blade receptacles because of the grounding pin so the home owner cut off or pulled the pin out of the plug in end of the cord. Now everything is back to normal with conversions being made from two blade to three blade receptacles. In new home installations for the past fifty years it has been mandatory to use the three blade grounding receptacles.

How do you troubleshoot three wire incandescent bulb Christmas tree light string?
Two wires are simply the AC power cord running the length of the string to power the next string. The third wire is a series circuit of all the lamps, connected to one side of the power cord at the plug end and the other side of the power cord at the socket end. The bulbs are low voltage lamps designed with a mechanism to short them out when they burn out so the other lamps stay lit and you can identify the failed one and replace it. If you remove a lamp the whole string will go out until it is replaced, because they are a series circuit.
