Seismic Support for Fire Protection Ventilation Cable Trays

Seismic Support for Fire Protection Ventilation Cable Trays

This article will explore the importance of seismic resistance in cable trays, discuss when seismic braces are necessary, and help you understand how to make informed decisions for your installation. The Easyex EFSCK Series Seismic Cable Restraint Kits are engineered to secure suspended non-structural components—such as ductwork, piping, conduit, cable trays, and HVAC equipment—against seismic, wind, and blast forces. Our cable tray, bolted framing, and seismic bracing are approved as one system through third party testing. Seismic braces can be flexible using aircraft quality cables, or rigid (solid) using steel sections such as pipe, angles, or strut channels. [pdf]

How much margin is needed for cable trays

How much margin is needed for cable trays

Pro Tip: Leave at least 15 to 20 percent spare capacity in every tray run, even if NEC fill limits allow more. Future cable additions are inevitable in any industrial facility, and pulling new cables through a full tray risks damaging existing insulation. Properly sizing your cable tray is critical for safety and compliance. Track counts, diameters, and weight to validate configuration quickly with live feedback. The calculator computes the cross-sectional area of all. In practice, tray fill, tray type, cable group, load capacity, segregation, and expansion margin must all be checked together. Smaller mesh provides better support for smaller cables. [pdf]

Electrical cable trays in explosion-proof locations

Electrical cable trays in explosion-proof locations

Cable Trays have been permitted in the hazardous (classified) locations in the National Electrical Code for Class I (flammable vapor and gases) since the 1978 NEC and have been used extensively in chemical plants, refineries, and other types of facilities. This article is about code requirements. Let's break down what you need to know about explosion-proof requirements for cable trays in these environments, keeping it simple and clear. Chemical plants have risks like explosive gases, dusts, or vapors. However, when it comes to enforcement, only the standard approved for the geographical area may be utilized. Hazardous locations are defined in Article 500 of the National E ectrical Code® (NEC®) 2020. Cable must ha minated with listed fittings. [pdf]

Why build fiber optic cable trays
