Cable trays residential

[wadesmith]

Is it permissible to use cable trays in residential work, say in the basement for running range, dryer, and other power wiring along an unfinished ceiling?

See 2002 NEC Section 392.3 Uses Permitted.

Tom Baker, I like the way that you answer a persons question. You give the Code Section, and then he/she will need to look it up in their Code book.
But the answer to his question, is "yes, you can use cable tray in other than industrial use".
I had never given it any thought, but in a very large home, it would be handy to use cable tray up in an attic. I have never seen it done, but I like the idea.

Here is a statement from UL which may assist you with your question:

NM Cable suitable for use in cable trays is appropriately marked. NM Cable marked for cable tray use may also have a supplementary sunlight resistant marking.

This is also specified in Section 334.10(4).

Has anyone ever seem NM cable with a rating for use in cable trays?
I've never seen it but then again I have never looked.

I'd have to bet that cable tray and special NM cable is more expensive than cheap NM and some staples.

I would use some ledger board and call it a day. It costs about $10 at Home Depot.

Code issues aside, cable tray sounds like expensive overkill for a home.
