Web11 Dec 2008 · A 500 MCM copper conductor is good for 380 amps. If the load is 380 amps or less, then you can use a 500 MCM. If the load is 381 amps or higher, you cannot use a 500 MCM. If you have not calculated the load, and you plan to use a 400 amp overcurrent device to protect a 400 amp panel, then a 500 MCM will not be sufficient. WebIn this system, 0000 AWG indicates a wire diameter of 0.46 inches, and 36 AWG indicates a wire size of 0.005 inches. There are 39-gauge sizes between these two sizes which you can get through logarithmic calculations. The ratio of different sizes is 1 to 92 in diameter.
