“Legends on the Line” is a series that stretches from National Lineman Appreciation Day (April 18) to Lineworker Appreciation Day (July 10), in honor of the brave linemen and linewomen who climb above and beyond to power our world.
Lineman Lingo from the Lineman’s Slang Dictionary
There’s a lot of work that goes into keeping the lights on. There’s also a lot of vocabulary.
One of the many reasons electrical linemen are unique is that through decades of making sure folks have access to safe and reliable electricity, they’ve developed the talk of the trade.
While guidelines for linemen terminology vary geographically within the industry, we’ve compiled a list of our favorite Lineman’s Slang Dictionary terms below.
