Planning Considerations

Cable support systems should provide the strength and working load capacity sufficient to meet the load requirements of the cable tray system and any future expansion. All work should be reviewed by a qualified structural engineer before implementing any installation.

All cable management and pathway apparatus should be selected, installed, and maintained in accordance with applicable industry standards including ANSI/TIA, BICSI, and NEMA. They should also be installed in compliance with all locally applicable fire safety and electrical codes, such as National Electric Code (NEC) in the United States and Mexico, The Canadian Electric Code in Canada, The International (IEC) in Europe, The British Standard (BS) 7671 in the United Kingdom, and NF C 15-100 in France.

There are many factors to consider when calculating cable support system capacities.

These include:

• Building overhead support structures.

• Trapeze capacities.

• Tray type and construction.

• Stacking multiple trays

• Installing the fiber optic tray system.

• Installing power busway system.

• The types of cables.

• The planned amount of cable runs.
