Busbar:Low impedance conductor to which several electric circuits can be separately connected. Switchboards include various devices such as fusible switches, or circuit breakers to feed smaller loads of electrical currents. This documentation provides more clarity with better representation of most of the commonly used switchboard constructions Metal thickness from 1.6mm to 3mm. If we are considering a miniature chassis, you may use a cable connection to a terminal. an individual motor starter within an MCC.
