Installing 2 -20 AMP Outlets in a Detach Garage From SCRATCH!
What happens here
The electrician connects the prepared 12/2 MC cable to the existing breaker panel. He strips the insulation from the black (hot), white (neutral), and green (ground) wires. The black wire is connected to a 20-amp Square D QO circuit breaker. The white neutral wire is connected to the neutral bus bar, and the green ground wire is connected to the ground bus bar. He emphasizes the importance of using 12-gauge wire for 20-amp outlets as per electrical code (whereas 14-gauge is for 15-amp).
Goal: Securely connect the circuit to the appropriate breaker and bus bars in the panel.
