Can someone tell me how to calculate the size of a power
cable? What are the factors involved in cable sizing?
Answer Posted / thowsif_emerson_csm team
Cable size is dependent upon the load(s) you wish to supply
power too. You have to know the maximum current you can be
expected to carry on a particular circuit BEFORE choosing a
cable.
Once you know the load, you need to choose a cable size
rated to carry at least that much current, preferably more
as a safety factor.
So if you are planning on running several electrical
devices with a combined current of 20 amps, you need a
cable sized to carry at least 20 amps, and slightly more.
To calculate the size of a power cable,pls refer the
