What happens here

Using a 5/16-inch nut driver, tighten the screws that secure the breaker to the bus bars. The speaker explicitly advises against using a power drill for this step to avoid over-tightening. It's crucial to use only one hand while working inside the electrical panel, even when the power is off, to prevent accidentally creating a circuit through your body if the panel were to become energized or if you were to encounter stored energy. Tighten one screw at a time, allowing the nut driver to "catch" the screw and secure the connection without excessive force.

Goal: Firmly fasten the circuit breaker to the bus bars.
