I have an old flat ribbon extension cord that recently lost its ground pin off its cap. Replaced it only to find that the ground wire (middle wire of the 3 wire ribbon) was broken at several spots thruout its 100 foot length. The cord was too useful for light loads (powers the boombox while raking leaves and such) to toss, so both ends got 2 prong plug/sockets.
The old ground wire was abandoned (snipped short to avoid contact with anything inside the plugs).
