  • One little code problem here. Assuming this was a 20 amp circuit, as the 12-2 yellow Romex would indicate it is a code violation to extend the line with 14-2. This is true even though the last light would never draw more than 1 amp. The issue is a 15 amp 14-2 wire, should not be protected by a 20 amp breaker. One way this could happen is if someone used a screw in adapter that supported a light and an outlet. Then, conceivably, someone could plug in something drawing over 15 amps and the circuit would be overloaded.

  • is it okay to use a different wire gage? Looks like you have 12-2 to the first lamp and then 14-2 to the second?

  • Great video! Exactly what I was looking for and makes this project look very easy. Looking for a little clarification on how you "pigtailed" the Wago connectors... I don't see any additional wire in the supplies list, so did you use leftover Romex wire to make the connection?

  • Excellent video. This is exactly what I was looking for to add an additional light in my storage room that has a dark area. It's much appreciated. Keep up the good work!

  • Good video. I know it's light and they don't have ground but I did the exact same thing in my attic and the junction box had a screw for ground so rather than letting the wire unattached in the box I screwed it in place there.
