What happens here

The main power feed from the primary panel consists of red and black hot wires, a white neutral wire, and a bare copper ground wire. The presenter explains that the red and black hot wires connect to the main lugs (bus bars) of the subpanel. The white neutral wire connects to the designated neutral bus bar, which, as previously noted, must be separate from the ground. The bare copper ground wire connects to the ground bar.

Goal: Correctly connect the hot, neutral, and ground feeder wires from the main panel to the subpanel

Tools and materials

  • Bare Copper Ground Wire — The incoming equipment grounding conductor
  • Black Hot Wire — The other incoming live power line
  • Red Hot Wire — One of the two incoming live power lines
  • Subpanel Ground Bar — Connection point for the ground feeder wire
  • Subpanel Main Lugs — Connection points for hot feeder wires
  • Subpanel Neutral Bus Bar — Connection point for the neutral feeder wire
  • White Neutral Wire — The incoming neutral return path
