http://www.eng-tips.com/gviewthread.cfm/lev2/11/lev3/47/pid/248/qid/52089 I need to determine the load rating for Square-Duct metal wireway (8"). The electricians walk on the overhead wireways on occassion and the question of whether or not the wireways provide adequate support has come up. I don't see a specification for this in the technical documentaion.
From my research so far, neither NEC article 376 nor maufacturers of wireway list a specification for point loading from personnel walking on the wireways.
Can you help me with this question? Thanks. E-C.net readers, what would be your suggestion?
