A bus bar is a set of terminals inside a service panel. Circuit breakers or fuses connect to hot bus bars, neutral wires connect to neutral bus bars, and ground wires connect to ground bus bars. Some service panels have separate bus bars for neutral and ground wires, like in Canada for example. Others only have one neutral/ground bus bar.
