NOTE                        : Current carrying capacities are valid under the following conditions.

In ground                 : 200C; buried in 70 cm depth; soil thermal resistivity 1 K.m/W; load factor 0.7

In Air                        : 300C; load factor 1.0

***                          : Flat formation; clearance between cables in air = 1 x cable outer diameter; in ground = 7cm

***                           : Trefoil formation
