was produced by our technical staff. We recognize the need
for a complete cable tray reference source for electrical engineers and designers. The following
pages address the 2014 National Electrical Code® requirements for cable tray systems as well as
design solutions from practical experience. The information has been organized for use as a
reference guide for both those unfamiliar and those experienced with cable tray.
Nearly every aspect of cable tray design and installation has been explored for the use of the
reader. If a topic has not been covered sufficiently to answer a specific question or if additional
information is desired, contact the engineering department at B-Line. We sincerely hope you will
find the Cable Tray Manual a helpful and informative addition to your technical library.
