Safety First: Turn Off the Power
Safety is the top priority when learning to wire a Legrand 341204-05/17. Always turn off the power at your circuit breaker or fuse box before you touch any wires. Find the breaker that controls the area you’re working on, flip it off, and use a voltage tester to ensure no electricity is flowing. This step prevents shocks or injuries.
Label the breaker if possible so no one turns it back on by mistake. Once the power’s off, you can explore how to wire a Legrand 341204-05/17.
Understanding the Wires in Your Box
Electrical boxes have different wires, and knowing them is key to how to wire a Legrand 341204-05/17. You’ll usually see:
- Black (Hot): Carries power from the breaker.
- White (Neutral): Completes the circuit back to the breaker.
- Bare or Green (Ground): Protects against shocks by grounding the system.
For a combination device like the RCD38, you might also have a load wire (another black) going to a light. Take a minute to identify these before starting how to wire a Legrand 341204-05/17.
What’s Inside the Legrand 341204-05/17 Instructions?
The 341204-05/17 document covers wiring for several radiant devices. For the RCD38, it explains a single-pole switch with a receptacle, plus a 3-way option. This guide focuses on the single-pole setup since it’s more straightforward for beginners. Knowing how to wire a Legrand 341204-05/17 starts with understanding its terminals: two for the switch (hot and load) and three for the receptacle (hot, neutral, ground).
The instructions are clear—turn off power, strip wires, connect them, and mount the device. Let’s break it down.

Step 1: Remove the Old Device
If you’re replacing an existing switch or outlet, start here for how to wire a Legrand 341204-05/17. With the power off, unscrew the wall plate and pull the old device out of the box. Look at how the wires are connected—label them with tape (like “hot” or “light”) so you don’t mix them up later.
Gently disconnect the wires from the old device using your screwdriver. Now you’ve got a clean slate to learn how to wire a Legrand 341204-05/17.
Step 2: Strip the Wires
The Legrand instructions say to strip wires to 1/2 inch. For how to wire a Legrand 341204-05/17, grab your wire strippers and remove 1/2 inch of insulation from the ends of the black, white, and ground wires in the box. There’s a gauge on the device to measure this, but eyeballing it works, too—keep it neat.
Stripped wires connect better, so take your time. This prep is a big part of how to wire a Legrand 341204-05/17.
Step 3: Connect the Ground Wire
Start with the ground for safety. On the RCD38, there’s a green screw or terminal for the ground wire. For how to wire a Legrand 341204-05/17, take the bare or green wire from the box, wrap it clockwise around the green screw, and tighten it with your screwdriver. If the device has a ground wire, connect it to the box’s ground with a wire nut.
A solid ground keeps everything safe, so don’t skip this step on how to wire a Legrand 341204-05/17.
Step 4: Wire the Switch Part
The switch part of the RCD38 has two brass screws—one for the hot wire and one for the load (going to the light). For how to wire a Legrand 341204-05/17, find the black hot wire from the breaker, wrap it clockwise around one brass screw, and tighten it. Then, take the black wire going to the light (the load), attach it to the other brass screw, and tighten that too.
This setup lets the switch control the light. It’s a key piece of how to wire a Legrand 341204-05/17.
Step 5: Wire the Receptacle Part
The receptacle has three terminals: brass (hot), silver (neutral), and green (ground, already done). For how to wire a Legrand 341204-05/17, connect a black hot wire to the brass terminal—either the same hot from the switch or a pigtail (a short wire) if your box has multiple hots. Attach the white neutral wire to the silver terminal, wrapping it clockwise and tightening it.
Now your outlet will work too. This dual wiring makes how to wire a Legrand 341204-05/17 so useful.
Step 6: Check Your Connections
Before you finish, double-check everything. For how to wire a Legrand 341204-05/17, make sure all wires are tight under their screws—no loose strands. Tug gently on each wire to test it. If anything’s loose, redo it. Loose connections can cause flickering lights or a dead outlet.
A quick check now saves trouble when mastering how to wire a Legrand 341204-05/17.
Step 7: Mount the Device
With wires connected, it’s time to put the device in the box. For how to wire a Legrand 341204-05/17, gently push the wires back into the electrical box, keeping them neat so they don’t pinch. Line up the device with the box’s screw holes, then use the provided screws to secure it in place.
Don’t overtighten—make it snug. This step finishes the core of how to wire a Legrand 341204-05/17.
Step 8: Attach the Wall Plate
The radiant series comes with a stylish wall plate. For how to wire a Legrand 341204-05/17, snap or screw the plate onto the device, following the instructions. It should click into place easily, covering the box and giving your setup a clean look.
A good wall plate is the final touch in how to wire a Legrand 341204-05/17.
Step 9: Turn On the Power and Test
Now, head back to the breaker and flip the power on. For how to wire a Legrand 341204-05/17, test the switch—flip it to see if the light turns on and off. Then plug something into the outlet, like a lamp, to check if it works. If both function, you’ve nailed it!
If not, turn the power off and recheck your wiring. Testing confirms how to wire a Legrand 341204-05/17 was done right.
Troubleshooting Tips
If something’s off, don’t panic. If the switch doesn’t work, check the hot and load wires—swap them if needed. If the outlet’s dead, ensure the neutral is secure. For how to wire a Legrand 341204-05/17, a voltage tester can help find where power stops. Always turn off the power before fixing anything.
