 Post subject: Conduit & Cable Tray Spacing

I have a standard from one company on conduit and cable tray spacing based on the certain types of signals, voltage levels, etc. carried by the cables in the cable trays/conduits. The length of the cables also plays a factor in the recommended spacing of cable trays and conduits. For example, a cable tray carrying RTD and low level DC signals running in parallel beside a cable tray carrying 120 VAC must be spaced at least 6" for every 100' that the cable trays are running in parallel. The motivation for this standard is to seperate high noise producing cables from sensitive cables.

What I am trying to find is where this standard came from? Alternately, are there similar, updated, standards written on the subject? I've looked through the NEC and CEC thoroughly but have limited access to ISA and IEEE standards.

Thank guys.

Paul Chriss
