Cables Notes
1. Where a conductor operates at a temperature exceeding 70ºC it must be ascertained that the equipment connected to the conductor is suitable for the conductor operating temperature.
2. Where cables in this table are connected to equipment or accessories designed to operate at a temperature not exceeding 70ºC , the current ratings given in the equivalent table for 70ºC thermoplastic insulated cables must be used.
