MASTER ELECTRICIAN DAD TEACHES HIS SON HOW TO INSTALL A SUB PANEL!
What happens here
The presenter reiterates the critical difference between main panels and subpanels regarding bonding. He shows a diagram illustrating that the neutral bus bar in a subpanel must NOT be bonded to the panel case. If a green bonding screw (which is designed to bond neutral and ground in a main panel) is present in a subpanel, it MUST be removed. This ensures the complete separation of neutral and ground, which is essential for safety and compliance in a subpanel setup.
Goal: Ensure proper unbonding of neutral and ground in a subpanel
