From PLSN | When Welding, Weld; When Not Welding, Don't Weld :
Of course we didn't have the Internet back then, and news traveled slowly to the midwest. As late as 1988 (that I know of) many were still using Twecos and welding cable as feeder.But after the 1984 Olympics in Los Angeles, when a production company asked the City of Los Angeles to allow the use of welding cable and Tweeco [sic] connectors, they said “No,” and its use was “outlawed” by the NEC. Most of us got the message and moved on to SC-type feeder cable, which is commonly called “entertainment,” cable and the use of welding cable was largely discontinued.
