American cable tray seismic bracing models

Fiber and communications infrastructure knowledge brief Published 16 Aug 2023

Prepared for preliminary research by the ROGER FIBRE knowledge desk. Confirm optical interfaces, port or core capacity, electrical input and output, enclosure protection, thermal design and installation limits against current standards and product documentation.

American cable tray seismic bracing is available through systems like Eaton B-Line/TOLCO, Loos & Co. Wire Rope/Cable™, and Cablofil kits, all designed to meet U. S. seismic codes and facilitate rapid, code-compliant installation.

Eaton B-

Line / TOLCO Seismic BracingEaton's B-Line series cable tray combined with TOLCO seismic bracing provides a fully tested, pre-approved system suitable for both new construction and retrofit projects. The system includes bolted framing, hold-down clamps, and guides, all approved for seismic applications. Eaton offers pre-approved assembly drawing packages and engineering services, including PE stamps valid in all 50 U.

S. states and Canada, to ensure compliance with building codes and standards. Installation is designed to be up to 50% faster than conventional methods, with no torque-wrench required for break-off bolts, simplifying field assembly. Loos & Co.

Wire Rope/Cable™ BracingLoos & Co. provides a Wire Rope/Cable™ seismic bracing system specifically for cable trays. These braces are pre-stretched to act elastically, functioning like a shock absorber during seismic events. Key features include: UL-listed, code-compliant for U.

S. building standards. Flexible, lightweight, and unlimited in length, unlike rigid compression braces. Color-coded standard sizes with minimum breaking strengths of 900, 1650, 4000, and 6600 lbs.

Components include the wire rope/cable, factory-attached stake eye, oval sleeve, and universal restraint clip (URC). Designed for rapid installation, typically one-third the time of conventional pipe, angle, or strut bracing systems.

Cablofil Seismic Bracing Kits

Cablofil offers seismic bracing kits for wire mesh cable trays, ideal for long runs and trapeze installations. Features include: Direct attachment to 3/8" threaded rods or predrilled concrete deck tabs.

Use of EZ B

N 3/8 connectors for sway bracing. Recommended spacing every 30 feet to maintain seismic compliance. Kits are compatible with Cablofil's wire mesh trays, which are lightweight, strong, and adaptable to complex routing configurations.

Design Tools and Compliance

Several manufacturers provide web-based design calculators to assist engineers in calculating brace requirements and ensuring compliance with the Authority Having Jurisdiction (AHJ). These tools simplify the selection of brace types, lengths, and attachment points based on project-specific seismic loads. All systems are designed to comply with IBC, ASCE, and OSHPD standards, and many include documentation for PE approval and quality assurance programs.

Summary

For American seismic cable tray applications, engineers can choose from: Eaton B-Line/TOLCO: pre-approved, fast-install, bolted systems. Loos & Co. Wire Rope/Cable™: flexible, pre-stretched, UL-listed bracing.

Cablofil kits: modular, wire mesh tray bracing for long runs. These systems provide code-compliant, efficient, and reliable seismic protection for electrical cable tray installations in the U. S.
