SpletSwitchgear is the largest of the three. It can be rated for up to 38 kV and can have current ratings up to 6,000A. Normally draw-out breakers are used, and therefore, access to the front and rear of the gear is required. Switchgear is tested to a different UL standard than panelboards and switchboards. SpletSwitchgear refers to a range of switches, circuit breakers, fuses, and other electrical/electronic equipment that serve to regulate, control, energize or de-energize a power system. Moreover, metal-clad switchgear is a type of switchgear, where all internal components are individually clad in separate metal compartments.
