What is the ground wire size for a level 3 distribution box

To figure out the size of the ground wire, you consult the copper grounding conductor size chart, and you see that you need an 8 AWG copper ground wire for 3 AWG copper wire (for 100 amps, you can use 8 AWG copper ground wire). The National Electrical Code (NEC) provides clear guidelines for ground wire sizing through Table 250. 122, but understanding how to apply these requirements correctly can make the difference between a safe installation and a costly code violation. 66 covers. Equipment grounding conductor (EGC) sizes for copper and aluminum wiring, from NEC Table 250. The NEC distinguishes between several types of grounding conductors, each with different sizing. Use this ground wire size chart after the calculator result to document which grounding path was used, what rating controlled it, and what bonding details remain before inspection. Ground wire size depends on the purpose of the conductor. This is also why people confuse it with being a 100 amp wire.
