How to choose copper and aluminium cable gauge size wrt. current rating

[panneerrajan]

Hi,

How to select and identify required cable gauge size (for Copper and Aluminium cable) with respect to current rating?

AWG std only mostly available in website. I need Cable sq.mm wise current rating chart.

for example:
45A 240VAC = Required Aluminium cable sq.mm? ( cable 4sq.mm/6sq.mm/10sq.mm)
45A 240VAC = Required copper cable sq.mm?

Please provide suggestion

Thank You
Rajan
