Main Bonding Jumper: Difference between revisions

Revision as of 02:53, 14 November 2022

Proper bonding - bond only at main panel, not subpanel. [1]. This is because the breakers are activated by current that includes the neutral, and if current flows through ground, the neutral may not have the current to trip a breaker. Depends on internals of the breakers. You still want the equipment ground connected to ground wires at subpanels, though..
The MBJ - [2]. Must be at main panel. Not subpanels.
