Sizes, weights and current rating

Manufacturer current ratings to IEC 60364-5-52, one circuit. In air at 40 °C: single core method F, three loaded conductors in trefoil; 2× and 3G method E with two loaded conductors; 3×, 4×, 4G and 5G method E with three loaded conductors; from 7 cores method E with two loaded conductors and the reduction factor of table B.52.17. In the ground: directly buried (method D2) or in conduit (method D1), at 25 °C and a soil thermal resistivity of 2.5 K·m/W; two loaded conductors for 2× and 3G, three for 3×, 4×, 4G and 5G. Voltage drop at cos φ = 1: single-phase for 2×, 3G and from 7 cores, three-phase for all other sizes. Resistance: the IEC 60228 class 5 maximum at 20 °C. A dash means on request.
