current-carrying capacity (Iz) of the cable. Reason: to require that the current carrying capacity of ring circuit cables be not less than 20 A and to require that the load current in any part of ring final circuits is unlikely to exceed Iz for long periods, see ...
to select the protective device on the basis of the ultimate fault current short-circuit breaking capacity for the maximum short-circuit fault current conditions. Operational circumstances may, however, make it desirable to select the protective device on the service short-circuit breaking capacity, e...

The load current in any part of the circuit should be unlikely to exceed for long periods the current-carrying capacity of the cable (Regulation 433.1.5 refers). This can generally be achieved by: (i) locating socket-outlets to provide reasonable sharing of the load around the ring (ii...
CableCalc BS7671 for iPhone is a mobile version of our popular Windows CableCalc software. This free app will calculate ring, radial and lighting circuits wired in twin and earth or 3 core and earth pvc cable up to 16mm. Calculations and checks include current carrying capacity, volt drop, ...
BS 7671 is the British Standard for cable sizing and capacity applies to low voltage cables with nominal voltages up to and including 1,000V AC, and 1,500V DC.
