At the big 400 amperes current, the voltage drop is less significant. To help you out, we have prepared 2 charts for running a 0-500 feet wire for 400 amp service at 120V and 220V voltages. The 1st one accounts for a 3% allowable voltage drop, while the 2nd one accounts for a less rigorous 10% allowable voltage drop.

A 50 amp sub panel will require at least 3 to 6 AWG wires. Here, I considered the distance around 55 feet. If the distance is longer, I suggest you use thicker and lower gauge wires. If the sub-panel distance from the main panel is 150 or 200 feet, you can use 4 AWG copper or 3 AWG aluminum or copper-clad wires.But let’s first look at what constitutes an equipment grounding conductor (EGC) and how it differs from the oft-misunderstood grounding electrode conductor (GEC) that connects noncurrent-carrying metal parts of the electrical service to the electrode buried in the earth.
