Cable Tray Installation Details
The document outlines specifications for various joint plates and connectors used in cable tray installations, including dimensions and quantities for each component.
Cable tray connecting plate size requirements
Cable tray connection plates are typically designed to match the tray width and side rail height, with adjustable options for widths up to 36 inches and side rail heights from 4 to 7 inches.Standard DimensionsTray Width Compatibility: Connection plates are generally available for cable trays up to 36 inches wide, with some manufacturers offering plates for wider trays depending on the system design .Side Rail Height: Adjustable splice plates can accommodate side rail heights of 4, 5, 6, or 7 inches, allowing flexibility for different tray profiles .Plate Length: The length of the connection plate is typically designed to span the joint between two tray sections, often matching the width of the tray to ensure proper alignment and load transfer. Exact lengths vary by manufacturer and tray type.Hardware: Connection plates are usually supplied with bolts, nuts, and washers, and bonding jumpers are not required for standard aluminum splice plates .Installation ConsiderationsSupport Spacing: Splice plates require supports within 24 inches (600 mm) on both sides of the joint to maintain structural integrity and comply with NEMA VE2 standards .Field Adjustments: Some splice plates are flexible and horizontally adjustable, allowing for minor alignment corrections during installation. Field cutting of the tray may be necessary to fit the desired angle or configuration .Load and Strength: The connection plate must be compatible with the tray's load rating. Wider trays or trays with larger rung spacing may require stronger or reinforced splice plates to safely bear the cable load .SummaryCable tray connection plates are designed to match the tray width and side rail height, with adjustable options for flexibility. For trays up to 36 inches wide, side rail heights of 4–7 inches are common, and proper support within 24 inches of the joint is required. Always verify the manufacturer's specifications for exact dimensions and load ratings to ensure safe and compliant installation .
