Under cabinet lighting (Valence lighting)
Hi Everyone,

I live in Toronto, Ontario. I am putting in new kitchen cabinets and backsplash. I plan on adding under-cabinet lighting and wanted to do the wiring now that the drywall behind the cabinets are off. I purchased these 12volt Xenon puck lights (Illume brand from Home Depot) which come with transformers for every three lights. These are supposed to be chained via pluggable wires. The challenge is that I want all the lights to be dimmed from the same switch and the wiring hidden as much as possible. I also have glass doors on couple of cabinets and did not want to showcase the transformers inside the cabinet.

So my plan was to run low-voltage lines behind the drywall to one cabinet where all the transformers will be located and connected to a box with line voltage which is fed from a dimmer switch. This would mean cutting out the pluggable low voltage wires and connecting them to 10 feet of low voltage wire (with wire screws) and tugging all of this behind the drywall. I would then just have a clean line poked into the drywall (and backsplash) from under each cabinet.

Is there a problem with this based on codes in Ontario? Any other suggestions are welcome.

I'm not sure on specifics, but I do know the transformer needs to be accessible.

The transformers will be accessible but part of the low voltage wireswill be behind the drywalls. As far as I know there are no junction boxes for low voltage lines, so I plan on just poking a hole in the drywall to pass them through.

I'm checking to see if there is anything in teh code that prohibits this.

Yeah that part I'm not sure. I'm guessing there may be a special type of plastic connector you need to use.

Burying splices of any kind is not a good idea! Just because it is only 12-volts doesn't mean it can't burn up! Actually it may be even more susceptible to going bad because depending on the type of load the lower the voltage the higher the amperage can be!
