What happens here
After stripping the wire, the individual conductors are connected to their terminals: the two hot wires to the 40 AMP breaker, the neutral wire to the neutral bus bar, and the ground wire to the ground bus bar. The video then shows the completed wire run extending to the garage where the EV charger will be located. To create necessary space for the new 40 AMP breaker, if the panel was full, tandem breakers (also known as twin breakers) are shown being installed. These smaller breakers allow two circuits to occupy the space of a single standard breaker, making room for the larger 40 AMP unit.
Goal: Complete all electrical connections and ensure adequate space within the panel.
