What exactly is secondary wiring in switchgear
Secondary switchgear, or secondary distribution switchgear, operates further downstream in the power distribution process. Its purpose is to de-energise set up for maintenance and repair to correct the faulty issues. At this. Although a common belief, Metal-Clad Switchgear (MC) wiring is not covered by the National Electric Code (NEC). Medium voltage electrical power distribution from generating stations to industries and consumers is divided into two main parts: primary and secondary distribution. There are three main types of electrical switchgear: low-voltage (LV), medium-voltage (MV), and high-voltage (HV).
