Great Response in EE Times - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

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.
