Cable Tray

You are running into HV and LV issues there. You need to check with you national and local requirements/code for guidance.

both issues are LV !

Sorry. In DoD 600V is the cutoff for what is considered HV. I was referring to interior wiring.

There are different guidelines that you have to study (eg fill area, supports etc) however NEC does allow 600V or less cables to be routed through the same tray so for you, though on the border, it is still OK.

Hhave a look at http://www.cabletrays.com/

thanks, GA

Yes! As long as you maintain a clearance of at least 300mm between the two cables.

<Assuming here that you are in the US because you are referencing 120VAC>

IIRC, the NEC will require that all of them must have the same insulation level and at the highest voltage in the tray / raceway. So when you run the 120V circuits, you must use wire that says 600V (or more) on the insulation. Most of the time that will be the case, i.e. THHN or THWN etc, but some appliance wire and "bell wire" is only rated for 300V, you cannot use that if it's in the same tray. The exception (sort of) is multi-conductor signal cables, but even then the outer jacket must be rated for the highest voltage in the tray. If you use conductors that say "TC" or "Tray Rated", that will have a 600V jacket.

Only if Caps Lock is turned off first.
