high-voltage medium voltage switchgear units

Medium-voltage: between 600V and 69 kV; High-voltage: between 69 kV and 230 kV; Extra-high voltage and ultra-high voltage classes are also defined in the ANSI/IEEE standards; however, NEC 2014 expanded the definition of low-voltage to include up to 1,000V. Medium-voltage switchgear is classified by the maximum voltage it can service.
