Bus Bar
A bus bar is a metal strip or bar used in electrical systems to distribute power, kind of like the main highway for electricity in a building or facility. Think of it as a central power distribution point that connects different electrical equipment together. Instead of having many individual wires running everywhere, bus bars provide a more organized and efficient way to distribute electrical power. They're commonly found in electrical panels, power distribution centers, and industrial facilities. When you see this term in a resume, it usually indicates experience with industrial or commercial electrical installations.
