The voltage ratings of terminal blocks are based upon the minimum spacing between electrically conductive parts line-to-line through air and over surface and line-to-ground through air and over surface.
Class A - Service, including deadfront switchboards, panel boards and service entrance devices.
Class B - Commercial appliances including business equipment and electronic data processing equipment.
Class C - Industrial, general
