Track Lighting power feed

Installing track lighting in a ceiling tile grid ceiling, I have two options for the power feed.

One option uses a "power module" where the leads stick out above the ceiling. I cannot figure out how to install a junction box for the wire splices above the ceiling. I don't think I can secure the junction box to the ceiling tile or T-grid. I don't see an easy way to drop a support from the ceiling. I don't think the code allows securing anything to the ceiling grid support wires.

The other option uses a "power module" where a romex cable could be directly wired above the ceiling to the power module so I don't need to worry about a junction box. Is Romex allowed in a commercial building in the suspended ceiling area? If so can it lay on top of the insulation above the ceiling tile? Without a junction box it is difficult to use flexible metalic tubing. If the romex and/or metalic tubing are required to be supported away from the top of the ceiling tile/T-grid, I will have to look more.

Any ideas? Thanks!

Re: Track Lighting power feed

Doug I tracks can be fed by a few ways. One is the way you mention, the others are end starter and corner fed. Unless this is a low voltage track the floating feed as it most commonly called is one that does require a box this could be a octagon supported by threaded rods. or by a piece of ply wood just laying over the top of the ceiling tile with a old work box cut into it. as the box is not there to support the track. The track is allowed to be supported by the rails for the ceiling. NM is not allowed in a commercial building above a suspended ceiling but you can use any other flex or MC cable to feed the track. also the end and corner starters do allow to be directly connected to them as they do have a 1/2" KO for this.
 
Re: Track Lighting power feed

Doug when I install track on ceiling grid I use these clips.

The hole at the top of the clip gives you a place to run a support wire or jack chain up to the building structure.

The clips are called IDS clips (Independent Support Clips) They are available from a couple of manufactures.
