Wire run length

[vbsparky]

I used to work in a factory installing RF welding
machines and had one of them pocket quick look
up cards for wire runs. where at a glance you looked up the amps and length of the run and got the size of wire needed. (also gave size for different wire insalation(THHN ect..))
well i lost it someplace.

where is a good chart i can use for this ?

Try this one:

Voltage Drop Chart

I personally don't like using charts, as they don't figure in other important aspects such as temperature and other derating factors. Voltage drop calculations are easy and generally don't required the need for a reference chart.
