  • How to select the model for the ground wire of a distribution box

    How to select the model for the ground wire of a distribution box

    The ground wire that runs with your circuit (the equipment grounding conductor, or EGC) is primarily sized by your breaker rating, with some exceptions such as voltage-drop adjustments. A 20-amp breaker needs a #12 AWG copper EGC. A 200-amp feeder. 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. Each DISTRIBUTION BOX and controller must be grounded. 26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. The EGC is the wire found in branch circuits, typically green or bare, and the GEC is the dedicated wire connecting the main service panel to the physical ground outside.
