A concern i haven't had to really consider down to
specifics before is the weight of a conduit run with wire installed
Best i can do is ring up what i'd call
hang weight>
http://www.interfacebus.com/Aluminum_Wire_AWG_Size.htmlfor example, via this chart, 4/0AL X 4 = 780lb's per 1000 feet
All fine and well, but what about the
pull weight during the install? i'm not sure how to calculate that, if there's
any calc at all?
I would think
any conduit install, be it individual clips, beeline, kindorf , or whatever , would need to be sized and installed toward a
pull weight
vs. the XXX required NEC attachments per ft.
Further, the roofing system it's all hung to has to be able to handle it too. Most industrial roofing here is required to have an XXX per foot
snow load capacity
am i off in the worry wart stratosphere here?
