Copper Pipe as Conduit

[Oxbusfrm]

I have recently seen some low voltage installations where installers used copper pipe (water pipe) as conduit. Customer relayed when the job was installed he didn't want FMC, PVC or steel for appearance, but preferred copper since it will patina. I cannot believe this is permissible. Thoughts?

If they ran a cable assembly through the pipe then it's just a sleeve. Copper pipe or any pipe for that matter can be used as a sleeve. Any photos?

What are you calling “low voltage?” Folks who deal with the entire range generally consider 600V or less as low voltage.

24V and below

24V and below

If it's CL2 (or 3) it's permissible.
