  • Requirements for jumper wires of cable tray expansion joints

    Requirements for jumper wires of cable tray expansion joints

    Whether you need extra wires (jumpers) depends on if your connecting plates are tested for grounding. If the plates are UL Classified, they are strong enough to carry electricity safely by themselves. In this case, you can skip the jumpers as long as the metal stays tightly. However, you must use copper bonding jumpers if the tray is painted or has expansion joints for movement. A connection resistance above 0. This subject. It is not necessary to install bonding jumpers in parallel with the standard rigid aluminum or steel one-piece metallic bolted side rail splice plates that are the connections between the cable tray sections.

  • What is steel cable tray made of

    What is steel cable tray made of

    Common cable trays are made of galvanized,, aluminum, or glass-fiber reinforced plastic. The material for a given application is chosen based on where it will be used. Galvanized tray may be made of pre-galvanized steel sheet fabricated into tray, or may be hot-dip galvanized after fabrication. When galvanized tray is cut to length in the field, usually the cut surface will be painted with a zinc-rich compound to protect the metal from corrosion.
