Is a wall girt a cable tray?

[mcbane]

I have a red iron with 8” and 10” wall zee girts. If I lay MC cable in the girts, would that count as a cable tray or do I still need to fasten it to the girts as if the cable might want to lift off of the girt web?

IMHO, Logic and common sense would imply that the troughs in your girts would be considered a cable way, but you are posting from California where we are enjoying a separate reality. Best contact your local Authority Having Juristdictino.

The specific definition of a cable tray, according to Article 392 (titled "Cable Trays") is this.
"Cable Tray System. A unit or assembly of units or sections and associated fittings forming a structural system used to securely fasten or support cables and raceways."
They're also required to be listed by UL or some other US recognized lab.
Z-girt doesn't meet those.

MC cable only needs to be fastened in place on 6' intervals anyway so what's the issue?

NO... Not a UL cable tray.
