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