Hardwired (uses dimmable transformer) LED strip light w wall switch?

last month

Dear all, thanks again for your help.

Our remodel project has come to the stage that the contractor started to put up drywalls. We told him that we will want to use a wall light switch (dimmer) to control our kitchen under-cabinet light. However, he just left a electrical wire on the drywall and that wire connects to the power source (120v) but the other end he did not connect to a 1-gang New Work PVC Electrical Outlet Box:

Is this correct?

Normally how does the electrical wiring look like when doing a "hardwired LED system" connecting to a wall light switch? Thoughts? Thanks!

This is what I found online:

In the future you’d be better served adding new related questions to your existing threads. How does the contractor envision the switching to happen? What do your plans show? The switch has to go somewhere, right now it sounds like he’s just planning for constant hot with a switch on the fixture but no one has done that in thirty years…

It seems that there are "wireless" wall switch (not a remote) that can control the LED strip light. Can anyone confirm this? Maybe that's what he was thinking? Thanks!

He has supplied a 120V whip that will connect to a 120V direct wire fixture similar to this <link>.

First you need to specify a fixture if you haven't.

Is your contractor supplying and installing the undercabinet lights?

1. You saw the wire when the wall was open. What was on the other end of the wire?
2. What's going to be attached to that wall? Wall-hung cabinets?
3. If there will be wall-hung cabinets, measured from the floor what's the distance to the bottom of the cabinets, top of the cabinets, and hole through which the wire protrudes?

@dennisgli I don't think that was clearly communicated before, so I will talk to him tomorrow about this. My hope is that they can purchase the under-cabinet lights (12v or 24v strip/tape light with dimmer-able tranformer) for us but I'm not very sure if they can do it (they are general contractor).

@wdccruise I saw the wire when the wall was open. One end of the wire is near the kitchen reange hood, and the other end is in the bedroom closet where I have my Legrand On-Q 30" Media Enclosure. I think he was thinking of getting 120v power from the Media Enclosure (which is about 4~5 feet away from the light switch location, in a bedroom closet), but I just don't see that he has connected the wire anywhere to a wall 1-gang New Work PVC Electrical Outlet box (for dimmer light switch)..

BTW this is the design by Inspired LED (InspiredLED.com, great service btw) which I have not shared with my GC! Does anyone know why he chose a 12V design over 24V design? Would a 24V design be better for my kitchen layout? Thanks!

"One end of the wire is near the kitchen range hood..."

You haven't provided a photo or drawing of your kitchen but after reading that statement, I'd assume that the wire is for the hood's fan and lights and that there is no circuit -- with or without a wall dimmer -- for under-cabinet lights.

I have IKEA Akrum (discontinued) kitchen cabinets and was somehow able to run wires behind the cabinets to the under-cabinet lights.

Without an electrical box for a dimmer switch you're not out of luck. You can use a wireless switch and receiver (example). The receiver would control the low-voltage transformer and the switch would be attached to the wall. No dimming, though.

But here's one with a dimmer.
