A contractor has proposed to install ladder type cable trays outdoors in an industrial facility for which to install 6.9KV, 480V, 208/120V power and control multiconductor cables as well as instrumentation cables. The trays will cross over a facility maintenance road. Do the clearance requirements of Art. 225.18 apply to overhead cable trays? If not, are there any other Codes or standards that would determine tray clearance requirements?
