What is the Main Bonding Jumper (MBJ) and How to Size it?
In an electrical panel or load center, the Main Bonding Jumper (MBJ) is the conductive connection that bonds (connects) the grounded conductor (neutral) to the equipment grounding conductor and the
What is the main bonding jumper and where do it find it in an electric
The main bonding jumper connects the service neutral wiring to the grounding electrode conductor (s) (GEC), and also to the service enclosure (panel box). By connecting these three
What is a Main-Bonding-Jumper? Why Do We Need it?
The main bonding jumper is critical to safety; circuit-breakers do not trip properly without this critical connection between the grounds and the neutral at the first means of disconnect.
Wiring Jumpers Part 1: What They Are & Why We Use Them
As mentioned before, a jumper is a conductor that is used to connect two or more points in an electrical circuit. [1m:6s] Jumpers are specifically designed for this purpose but are not required in many cases.
