I am working on a project to provide networking data to a food production line. All of the power (both 120 & 220 volts is run in a chase approx. 15' long and the chase is roughly 8"s tall and 6"s wide. Instead of having my networking Keystone Jacks cut into a sheetrock ceiling tile above the production line I am wondering if I can run 4 CAT-6 SHIELDED network cable in the same chase that contains the 120 & 220 Romex and just cut in my keystone jacks with stainless steel wall plates on both sides of the food production line in the proper places I need to to be able to connect 4 video controllers to the store network?
There are suppliers of CAT 5 Ethernet cable (not sure about CAT 6) that is rated for 600V and is "PLTC" listed. PLTC means Power Limited Tray Cable and with that listing, it can be run in the same raceway as any other cable up to and including 600V. It is not going to be the cheap cable you can get at a hardware store, it is "industrial grade" stuff that you will have to buy from an industrial distributor that specializes in control system networking. Allen Bradley makes and sell it for sure, there may be others.
There are other 600V rated Ethernet cables available, but most of them are listed as "AWM" (Appliance Wiring Material). The difference is, AWM requires it's own raceway but can enter and terminate in an enclosure with other power circuits up to 600V, it just cannot be RUN with them in a raceway.
