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.

Tools and materials

  • 20-Amp Circuit Breaker Square D QO — Overcurrent protection for the new 20-amp circuit
  • Breaker Panel Square D QO — Source of power for the new circuit
  • Screwdriver — Tightening terminal screws on the breaker and bus bars
  • Voltage Tester — Verifying that the power is off before working and testing live circuits afterward
  • Wire Strippers — Stripping insulation from individual conductors

for the outlets. Now we you need to install 122 wire 12 gauge. When installing a 20 amp outlet, it is for the code. If it was a 15 amp outlet, you can install 14 gauge. But since it's 20 amp outlets, we are doing uh 12 wire. And you can see I'm tucking my wires. Here's a circuit breaker, guys. It's a square DQO panel. I'm showing you guys how the breaker looks like. And right now, I'm pushing in the breaker and checking my work. And as you can see here, here's a recap, guys, of the wires. So, the black wire is also known as the hot wire. That's the power. The white wire is the neutral. And the green wire is the ground. So, GG's, always remember that. So, you can see my wire where it's going. And the white, the neutral is on the bottom. The green's on the right hand side. And yes, there is my MC wire. I strapped it along following the ROMX. You always want to follow whatever paths the wires are currently previously. And that is an LB there. Now, we didn't necessarily have to run an LB, but we did an LB because it looked cleaner. Uh especially this was our first outlet. And here is a GFCI outlet, guys. And this is the line side. So, anytime you install a GFCI outlet, there is a line and a load. And the line is always going to be your first outlet for power. So, it's always important to establish which is your line and your
