Specifies requirements for metal cable trays and associated fittings designed for use in accordance with the rules of Canadian Electrical Code, Part I and the National Electrical Code®
The load capacity of the cable trays according to the support width can be read off in the diagram using load curves – here, shown as an example for a cable tray with the tray widths 100 to 600 mm.
They must be anchored to the structural steel and not to the tray itself. The tray is not designed to withstand the substantial side pressures that can be applied during pulling.
Cable tray systems are to be installed so they are accessible. If possible 300mm minimum should be left above or between installed systems to allow for cable
Where cable ladder and cable tray support systems are fixed to primary supports (e.g. structural steel work or elements of the building) it is important to ensure that the primary supports are strong
Cable trays with a rail height of 60 mm, in widths of 100 to 300 mm (RS 60.100 OV - RS 60.300 OV) are used for ceiling and wall mounting. The cable trays are
Mounting structures will be welded to inserts or beams, with welding to beams requiring approval. Spacings, load limits, and heights are specified for horizontal
