Connect each fixture to its own control panel using 14/2 or 12/2 cable depending on the circuit amperage. Ensure the power is turned off at the breaker before starting any connections. Use wire nuts rated for the number of conductors and current load for safe joins.
Route the conductors through approved boxes with enough space for all terminations. Label each wire to keep track of the path from the power source to each fixture. Maintain proper grounding by attaching a bare or green wire to each metal enclosure.
Test the setup incrementally by energizing one panel at a time. Verify that toggling each control affects the intended fixture without causing flicker or shorts. Inspect each junction point for secure connections and tight clamping of cables.

Use 14/2 cable for a 15-amp circuit or 12/2 for 20-amp circuits to connect each fixture to its control panel. Strip the outer sheathing carefully to avoid nicking the conductors, and keep at least 6 inches of free wire inside the box for secure terminations.
Install metal or plastic enclosures with proper mounting to hold the panels. Make sure each box is flush with the wall surface and firmly anchored to studs to prevent movement when toggling controls.
Connect the hot conductor to the first terminal on each panel and run a traveler conductor between the two panels. Use color-coded cables, typically black and red, to avoid confusion when connecting each path.
Join the neutral conductors together inside the enclosure using wire connectors rated for three or more wires. Ensure all connections are tight, and test for continuity before covering the boxes.
Attach the grounding conductors to the green screw or grounding bar inside each enclosure. If the panels are metal, bond the enclosure to the ground wire to prevent electric shocks and ensure compliance with safety codes.
Check the operation sequentially by energizing the circuit one panel at a time. Toggle each control to confirm that each fixture responds correctly and that no unintended paths are energized.
Perform a final inspection to verify all cable clamps are secure, conductors are properly routed, and boxes are covered with faceplates. Label each panel for easy identification of which fixture it controls for future maintenance.
Choosing the Right Wires and Switches for a Two Light Setup
Select 14/2 conductors for circuits rated at 15 amps and 12/2 for 20-amp circuits to ensure adequate current capacity. Avoid undersized cables, which can overheat and create fire hazards.
Use copper cores rather than aluminum for improved conductivity and reduced resistance. Aluminum can be prone to expansion and loosening at terminals, which may cause intermittent operation or overheating.
Choose toggle or rocker panels rated for the circuit load with a minimum of 15 amps. Verify that the terminal screws are compatible with the conductor gauge to maintain secure connections.
Insulation and Sheathing Considerations
Opt for NM-B or THHN insulation suitable for indoor runs. NM-B provides flexible installation in walls and ceilings, while THHN is better for conduit paths and longer distances.
Color Coding and Organization
Mark black or red conductors for hot paths and white for neutral. Proper labeling reduces mistakes during installation and simplifies future maintenance or troubleshooting.
Include a dedicated ground conductor attached to all metallic enclosures. This creates a continuous safety path and meets electrical code requirements for residential circuits.
