Electrical wire sizing for distance
WebA wire’s electrical resistance depends on its length and thickness. Longer wires provide greater resistance than shorter wires. Given two wires of the same length, the thicker wire would have smaller resistance than the thinner wire. (e.g., At 25° C, AWG 4 wire has a resistance of .2485Ω for 1000 feet, while AWG 40 wire has a resistance of ... WebFeb 18, 2024 · Step 1 – Size the overcurrent device in accordance with 210.20 (A) and 215.3.
