Electrician Jargon

My father is an electrician and over the years I've picked up on much of the jargon that electrician's use. The words in this vocabulary might baffle you, but are used daily by electricians all over the United States:

Phrase Meaning
11B box A 4 11/16″ square junction box.
1900 box A 4″ square junction box.
8B An eight-sided junction box.
armor-clad Armored cable that comes preloaded with conductors. This type of cable has a reputation for being unsafe.
anti-dog A bubble level that attaches to the end of a pipe.
back stabber A person that uses the "quick-connect" slots in the back of a duplex outlet to install wires instead of the screw terminals on the side. Such a person is said to be lazy; it saves a few seconds, but derates the outlet to only 15 amps. Bob Vila has a nice picture illustrating the difference.
