These ratings are generally greater than those ratingsgiven in Table 4D2A.Regulation 433-02-04 is amended to require the ratings of ring circuit cables to be not less than 20 A instead of 0.67 In.Other, generally editorial, changes have been made.This amendment comes into

9、207 for which the minimum is 1.5 mm2. Such ring final circuitsare deemed to meet the requirements of Regulation 433-02-01 if the current-carrying capacity (Iz) of the cable is notless than 0.67 times the rated current or the current setting (In) of the protective device 20 A, and if, under theintend
10、ed conditions of use, the load current in any part of the ring is unlikely to exceed for long periods thecurrent-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 requirethat the load current in any part of r
