I'm having my basement finished, and I am going to run conduit for low voltage (network) wiring in a week or two myself. I have been planning on using gray PVC electrical conduit like this, since it's available at Home Depot in many sizes with wide-bend fittings, and it seems like it'd be easier to mount and fish wires through a couple bends with it than with the flexible ribbed conduit. However, when researching the project I came across this video for flexible conduit which states "bright orange components clearly signify a low-voltage installation." So I have a few questions:
Can I use gray PVC conduit for low-voltage electrical stuff? I know it's not kosher to use white PVC for high voltage. Using gray for low voltage seems like it should be OK, since the stuff inside would be less dangerous.
Should I color-code the low voltage conduit, and if so what color should I use? Orange (that's the color of the low-voltage brackets/mud rings)? Could I spray paint the gray conduit?
