How long is the cable tray jumper

Cable tray jumpers are used to electrically bond and connect sections of cable tray, with standard lengths typically ranging from 6 inches to 36 inches depending on the application.

Standard Specifications

Length: Standard Snap Track bonding jumpers are 36 inches long, designed to span discontinuities in expansion splices and adjustable fittings, though optional lengths are available upon request. Smaller jumpers, such as those with 6-inch lengths, are also used for shorter connections or specific routing needs. Material: Jumpers are typically made from durable conductive metals to ensure reliable grounding and electrical continuity.

Aluminum and copper are common materials, with some products rated for high current applications (e.g., 2000 Amp aluminum bonding jumpers),. Hole Configuration: Many jumpers feature pre-drilled holes for mounting. For example, a 6-inch jumper may have two 3/8-inch holes spaced 1 inch apart to facilitate secure attachment to the cable tray.

Color Coding: Standard bonding jumpers are often green, indicating grounding, though other colors may be available upon request. Installation: Jumpers are installed to maintain electrical continuity across tray sections, especially at expansion joints, fittings, or transitions. Proper installation ensures effective grounding and reduces the risk of electrical hazards.

Considerations

Length Selection: Choose jumper length based on the distance between tray sections and the type of fitting or splice. Longer jumpers are used for expansion joints, while shorter jumpers are suitable for direct connections. Compliance: Ensure that the jumper meets relevant electrical codes and standards for grounding and bonding in your region.

UL-listed or CE-marked products are recommended for safety and compliance. Flexibility: Some jumpers are designed to allow flexible routing around obstacles while maintaining a clean cable pathway. By selecting the appropriate length, material, and hole configuration, cable tray jumpers provide reliable electrical bonding and maintain organized cable management across installations.
