What size ground wire should be used for a level 3 distribution box
26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. 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. Proper grounding conductor sizing is critical for. The NEC ground wire size chart defines the least instrument grounding conductor size for single and 3-phase systems according to conductor size for ranges such as 14 AWG to 4000 kcmil. This is also why people confuse it with being a 100 amp wire.
