| * Based upon a K value of 143, taken from BS7671 table 43a. For short circuit durations of other than 1 second, divide the tabulated ratings by square root of t, where t is the duration in seconds. This calculation is valid for t between 0.2 and 5 seconds. | |||||

| Current ratings are based on a "single
circuit"in accordance with the IEE Wiring Regulations BS7671,
Table 4E2A. Where a conductor operates at a temperature exceeding
70°C it shall be ascertained that the equipment connected to the
conductors is suitable for the conductor operating temperature. (BS7671
reg 512-02). The above-tabulated current ratings should be multiplied
by the rating factor (0.8) when conductor-operating temperature has
not to exceed a recommended terminal temperature of 70°C. Important: All information is believed to be correct at time of issue. TPWCC reserve the right to alter dimensions, specifications and materials at any time under its development programme. |
