Foot Traffic? [from another electrical mesage board] - 04/08/03 10:18 PM

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?
