Re: power cable sizes

Rules varry from country to country..
Here (sihgle phase) the general rule is 2.5mm² for power points and 1.5mm² for standard (230V) light points.
In this case for partially surrounded (in thermal isolation) coper wire, circuit brakers are 20A(max) for 2.5 and 16A(max) for 1.5.

You have to check "Wiring Rules" for Pakistan to find out what are the rules in your country..

For PVC isolation cable with three wires loaded (3phase systems): PP 4.0 sq mm is 28A max, for 6.0 sq mm is 36A max.
Also you should consider nuber of wires loaded, number of cables, type of installation: A, B, C, D, E, F,G, H, J, K, L and Q.

Re: power cable sizes

one can also specify in terms of "Gauge" ...that specifies...the size and current carrying capacity...
