Appropriate Implementation of the Main Bonding Jumper and the Equipment Grounding Conductor: A Deeper Look Into a Suitable Ground Path

In many wye electrical systems, the function of the ground and neutral conductor is not differentiated because they are incorrectly joined. From a technical point of view, a connection between ground and neutral shall only be made once, at the main electrical panel; otherwise, those conductors should form two different paths. Although the implications of this connection are often seen as shallow and a misinterpretation of the National Electrical Code (NEC) makes it acceptable, this matter is actually very significant when it comes to protecting humans. Thus, it is important to take a deeper look into how to make a suitable ground path, which is the scope of this article.
