Ambient temperature: 30ºC Conductor operating temperature: 90ºC 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

Conductor operating temperature: 90ºC r = Resistive Component x = Reactive Component z = Impedance Value * Spacings larger than one cable diameter will result in a larger voltage drop. 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
