ELECTRICAL CHARACTERISTICS

Current Carrying Capacity and Voltage Drop Ambient temperature: 30ºC Conductor operating temperature: 90ºC 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 (see also Regulation 512.1.2). 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 (Table 4D1A) must be used (see Regulation 523.1). The above table is in accordance with Table 4E1A of the 17th Edition of IEE Wiring Regulations.

The above table is in accordance with Table 4E1B of the 17th Edition of IEE Wiring Regulations. For cables having conductors of 16mm2 or less cross-sectional area their inductances can be ignored and (mV/A/m)r values only are tabulated. For cables having conductors greater than 16mm2, cross-sectional area the impedance values are given as (mV/A/m)z, together with the resistive component (mV/A/m)r and the reactive component (mV/A/m)x. The above paragraph is extracted from Appendix 4 of the 17th Edition of IEE Wiring Regulations. AMBIENT TEMPERATURE 25ºC 30ºC 35ºC 40ºC 45ºC 50ºC 55ºC 60ºC 65ºC 70ºC 85ºC 90ºC 95ºC
