A distribution box is the heart of any electrical system. It takes the incoming power and safely distributes it to different circuits throughout your building. This connection. What's a neutral?The IEEE defines a Neutral as the conductor that has an equal potential difference between it and all other conductors (hot wires). An example of a neutral wire would be the white/gray wire of a single-phase 120/240 volt system or a three-phase 4-wire Wye system, Figure 1-1. Open neutral can result in. The protective grounding system, which includes conductor grounds and worker bonding, must be engineered to protect workers from hazardous voltages that can be created by line reenergizing, lightning, or induced oltage.
