Where a conductor operates at a temperature exceeding 70C it must be ascertained that the equipment connected to the conductor is suitable for the conductor operating temperature (see Regulation 512.1.2 of the 17th Edition of IEE Wiring Regulations). 2. Where cables in this table are connected to equipment or accessories designed to operate at a temperature not exceeding 70C , the current ratings given in the equivalent table for 70C thermoplastic insulated cables (Table 4D4A) must be used (see also Regulation 523.1 of the 17th Edition of IEE Wiring Regulations). The above table is in accordance with Table 4E4A of the 17th Edition of IEE Wiring Regulations.
