Because of the insufficient current rating, using 1.5mm will, at best, result in a voltage drop and, at worst, ignite a fire. For a socket circuit ring main, a minimum cable size of 2.5 sq mm is required (and 6 for spur circuits).

Spurs away from the RingThere is no restriction to the total number of fused spurs; however, if a fused spur supplies socket outlets, the minimum cable diameters listed below must be employed. 1.5 mm 2 for copper cables with pvc insulation. For tiny copper conductor cable, use 1 mm 2.
A conductor with a 1.5 mm circular cross-section has a current of 5.5 sin (4 × 1010t)μA.
