Where an earth bonding plate fits

Ground returns from lamps, motors and control units all have to reach battery negative. An earth bonding plate collects a group of them at one point, so the harness has a single, defined ground location to check in service instead of returns spread across the body or frame. On the NBX‑966 the harness lands on plug-in connectors, so a ground group is disconnected and re-made at the connector.

Choosing the NBX‑966

IP5X declares dust protection and no water rating. If the point is a sealed junction with no fuse or relay inside, see the NBX‑965 sealed junction box (IP65). If it also has to hold fuse modules, relay modules or terminal blocks, see the NBX‑968 sealed electrical box (IP54).
