    The function of primary wiring in a power distribution cabinet

    Primary wiring: used to realize the transmission, distribution and control of electric energy, directly connected to the power supply and power equipment, responsible for the transmission and distribution of electric energy, and is the main circuit of the power system. At its core, primary wires are the unsung heroes of any electrical setup. They are built to carry. The main feeder is the three-phase backbone of the circuit, which is often called the mains or mainline. The mainline is normally a modestly large conductor such as a 500- or 750-kcmil aluminum conductor.
