![]() I'm getting this info from an uglys handbook, and I'm just an apprentice, so someone with more experience can chime in, but this is my understanding.Īlso, I'm pretty sure breakers don't trip until they hit like 125% load, or are thermally triggered, ie too thin a gague and too many amps heating up the wire should trip it. ![]() In that case, you can up the breaker to a 50 and 80% of that is 40 amps, but the wire can stay the same. Wire Circular mils 2 x x I x L / (Allowable Voltage drop of source voltage) Calculating Wire/Cable Size formula for Three Phase Circuits. Now idk where you're getting the information of breakers tripping at those figures, but the rule of thumb is that if it is going to be a continuous load, you can only use 80% of the breakers capacity, so on a 40 Amp breaker, you'd only want to run 32 amps through it if it's going to be on for multiple hours. You may also check the Wire & Cable Size Calculator (Copper & Aluminum) in AWG (American Wire Gauge) Calculating Wire/Cable Size formula for single Phase Circuits. Someone can correct me if I'm wrong here, bu the wire should be able to handle all of those amps and probably even some more before its going to over heat. American wire gauge (AWG) size calculator and chart. ![]() Unless specifically permitted in 240. Example: A windlass rated 80A is 25’ from the battery. D Intersect CURRENT IN AMPS with LENGTH IN FEET to identify the wire size. The if it's UF, #8 is good for 40 amps, if it's thhn with its good for 55 amps, so thhn 10 gague is good for 40 amps. Wire Ampacity Size Table Small Conductors. Follow down the column until you find your circuit’s LENGTH IN FEET. It depends on what material the insulation is made out of.
