I'm running 6 low voltage "puck" type lights under my kitchen counters. They are 12VAC 20watts each.

I'm using a magnetic 200W 12VAC transformer.

The lights will be switched on/off, there won't be a dimmer.

The lights will be placed in three physically separate areas, but all on one circuit. In one area, I will have a single light, in another, 3 lights, and another, 2 lights. I can't just loop the wire from light to light as there is a stove, sink and other "gaps" which prevent this.

I could "home run" three pairs of 10 or 12 gauge stranded wire back to the transformer.

But I'm considering running 12/2 bx in a loop from the transformer to three Jbox's (daisy chained) that will be located in the ceiling above each "drop" - where the lights will be located. From each of these Jboxes, I was going to run 10 or 12 gauge stranded wire down to the lights. I figure the benefit of 12/2 bx is it will minimize voltage drop plus it's shielded.

Anyone have an opinion on this? Or any experience with low voltage kitchen lighting?

Thanks,

Phil

Junction boxes & Daisey Chain soundds OK to me.

Keep in mind that any concealed wiring must be wired as if it is regular line voltage. This means you would need one of the following types of cable, non-metallic sheathed cable (commonly called sheathed electrical cable or NMB ), Type MC Metal Clad Cable, or Armored Cable (sometimes called BX). There are other methods you could use, but they would be more expensive and laor intensive.

BTW, concealed would mean behind cabinets, in walls, up in the attic, etc.

Thanks for your reply.

The shielded wire question is an issue. I realized this and tried my best to find a class 2 transformer which would have enabled me to use unshielded wire, but couldn't work it out.

The puck lights aren't mounted to j-boxes or round light boxes or anything, they just sort of clip into a 2 3/8" hole drilled into the cabinet under panel. I can't seem to figure a way to use junction boxes in the wall behind the cabinets and run shielded wire right up to the lights.

I need to think this through some more.

Thanks.
