Just a ?- Are you guys talking about the pigtail splices? I never heard that expression-butt connector.
Wow that is impressive, I thought everyone knew the term.... An Electrical Joke that actually stuck to something, also refer to as Butt Crimp Connectors, Butt-Splices, and Etc... Who knew connecting to ends of wires together could be so juvenile

Glad to see I'm not the only one that belives wiring should be taken a little farther than a $0.15 connection, when you have the ability to do so!!
