The table in arrl manual warns that the figures are approximate and can vary dependent on the producing tolerances. If you do not have a chart handy, you don't really want a formula.

Records about 35 mm2 cu cord in accordance strцberg ttt 35mm2 copper twine can take continuous contemporary of 170a on free air and two hundred a on ground. The smaller the wire is. There are some very particular exceptions. The better the resistance is.5 a three 6 10 16 25 .75mmі 1mmі 1. The cord heats up greater. The former is why you want higher-temperature insulation and/or bigger wires for use in conduit.Five a ten 16 equipment wires mm^2 zero. When the resistance is higher. Don't do this except you're positive that your use suits one of these exceptions. The latter is why you must use larger wire for long runs. Dc resistance of the wiure is zero. Where use of smaller twine is authorized.5 2. You could by no means go incorrect by using the usage of larger twine. Mains wiring modern rankings in mains wiring there are two considerations. Voltage drop and heat buildup. And there's greater voltage drop within the wiring.Seventy five 1.5 2.5mmі zero. The cord can manage 5 ka short circuit contemporary for 1s. Neither effect could be very great over very quick distances.52mohm/m.0 1.Five 0.
