These cables are intended for use in the wiring of switch control metering relay and instrument panels of power distribution switchgear and internal connections. They are intended for use at alternating voltages not exceeding 600V to earth and direct voltages not exceeding 1000V to earth. When installed in the equipment they are suitable for wiring circuits for which the prescribed alternating test voltage does not exceed 4kV RMS for 1 minute. By being approved to three international standards Tri-Rated cable is suitable for equipment installations required to meet both North American and European wiring regulations and codes of practice.
