What happens here

After the power is confirmed off, use a multimeter to double-check that no voltage is present in the sub-panel. This is a critical safety step. Following this, when installing the new sub-panel, it is imperative to install a separate ground bar. According to electrical codes, grounds and neutrals must be kept separate in a sub-panel to prevent current from flowing on the ground path during normal operation, which is a safety hazard.

Goal: Confirm safety by testing for voltage and prepare the new sub-panel according to code by separating grounds and neutrals.

Tools and materials

Ground Bar — To provide a dedicated bus bar for all ground wires, separate from the neutral bar
Multimeter — Verifying that the power is off and no voltage is present
