What happens here

The electrician runs the MC cable from the panel to the location of the first outlet. He uses an LB conduit body for a cleaner appearance, though it's noted as not strictly necessary. He prepares a metal electrical box and pulls the MC cable into it. He then wires a GFCI (Ground Fault Circuit Interrupter) outlet, connecting the incoming power (line) wires to the designated "line" terminals and grounding the metal box. He explains the distinction between "line" (incoming power) and "load" (outgoing power to subsequent outlets) terminals on a GFCI.

Goal: Correctly install and wire the first GFCI outlet, ensuring it is properly grounded and ready to protect downstream outlets.

Tools and materials

  • Conduit — Protecting the MC cable in certain sections
  • GFCI Outlet — Providing ground fault protection for the circuit
  • LB Conduit Body — Making a clean 90-degree turn for the conduit/cable run
  • Metal Electrical Box — Housing for the GFCI outlet
  • Screwdriver — Connecting wires and mounting the outlet
  • Straps/Clamps — Securing the cable and conduit to the wall/framing
  • Wire Strippers — Preparing wire ends for connection

What they say

Hide

establish which is your line and your load. And as you can see, we have installed the line and the load. Uh, make sure to always ground. We install metal boxes. And anytime you install a metal box, you must ground it. And right now, you can see these are finished. Guys, all outlets in a garage need to be GFCI protected, which stands for ground fault circuit interrupter. Here we are showing you a recap. I am showing you where I ran my wire. So, you can see this is a three bay garage. And above here is where I came to the other room. I ran the wire above the garage door, nice and hidden. And you can see right here, our MC is strapped. our LB. Like I said, we didn't have to run an LB, but we ran an LB because it was the first outlet, and we're gonna eventually had two wires coming out of it, as you can
