I was going through the 2014 code book to size a 400 amp underground service when I came to the conclusion that I might be able to use parallel 1/0s. Let explain and maybe ... Wire Ampacity Calculator Enter the information below to calculate t 400 Feet: 2 Or More Wires: 250 kcmil Copper Wire: 2/0 AWG Copper Wire: 500 Feet: 2 Or More Wires: 300 kcmil Copper Wire: 3/0 AWG Copper Wire: We see that we need increasingly thicker wires if the wire length increases and for lower voltages. Here is what size wire we need for an 80 amp circuit 200 feet away at a 3% allowable voltage drop: … Here is the full step-by-step calculation of how t...
