Route piping over or under cable trays?
Route piping over or under cable trays?
(OP)
Which is the better practice in the event that piping must cross cable trays?
Is it dependent upon the pipe joining method or insulation? If there's a chance of leakage I would think that routing the pipe under the cable trays would be better. But...
Does the radiant heat from piping impact routing underneath cable trays?
This is just a general question because I came across another piece of literature that I wanted to investigate further.
Thanks

RE: Route piping over or under cable trays?
Couple reasons:
1) In the world I operate in, wet utilities require a lot more maintenance and attention than electrical utilities do. Assuming you're talking about hung cable tray (not cable tray on the floor..) putting wet utilities underneath makes them a lot easier to access and maintain.
2) If there's a leak, I'd rather not spray my electrical service with solvent or paint or both
3) Replacing cables inside tray can be done in many cases without accessing the tray along it's full length. I.e. cables can usually (not always) be pulled from one end, or at least pulled through straight sections between tray elbows/tees without uncapping the whole tray. Wet utilities are usually harder to replace in this manner, so it benefits everyone to maximize access to them.
If radiant heat or possible high pressure spray from a leaking fitting is a problem, it is relatively easy to shield the cable tray from either of those hazards.

I used to count sand. Now I don't count at all.

Radiant heat does not just go up.
