Notes
- Where a conductor operates at a temperature exceeding 70oC it shall be ascertained that the equipment connected to the conductor is suitable for the conductor operating temperature.

- 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 pvc insulated cables (BS6004, BS6346) shall be used.
