Abstract
A cable tray assembly includes first and second cable tray sections each including a base and rails extending transversely from longitudinal sides of the base. A splice plate assembly is configured to engage the first and second cable tray sections for attaching the first cable tray section to the second cable tray section. A bonding jumper is attached to the splice plate assembly such that a first end of the bonding jumper is attached to a first splice plate and a second end of the bonding jumper is attached to a second splice plate whereby the bonding jumper is attached to the cable tray sections without forming holes in the cable tray sections. The splice plate assembly and bonding jumper providing an electrically conductive link between the cable tray sections.
Claims17
A splice plate assembly for use in attaching cable tray sections together to form a cable tray assembly, the splice plate assembly comprising:
- a first splice plate configured to be secured to a first cable tray section, the first splice plate including a planar base and a tab extending transversely from the planar base;
- a first connector on the first splice plate for securing the first splice plate to the first cable tray section;
- a second splice plate coupled to the first splice plate and configured to be secured to a second cable tray section to attach the second cable tray section to the first cable tray section, the second splice plate including a planar base, a tab extending transversely from the planar base of the second splice plate, each tab defining a fastener hole for attaching to ends of a bonding jumper to provide an electrically conductive link between the splice plates;
- and
- a second connector on the second splice plate for securing the second splice plate to the second cable tray section,
- wherein the first and second connectors each comprises a set screw for engaging an exterior surface of the rails to secure the splice plates to the cable tray sections without forming a hole through the cable tray sections.
A splice plate system for use in attaching cable tray sections together to form a cable tray assembly, the splice plate system comprising:
- a first splice plate comprising:
- a planar base having an interior surface and an exterior surface opposite the interior surface;
- a first tab extending transversely from the planar base outwardly from the exterior surface;
- and a second tab extending transversely from the planar base outwardly from the exterior surface, wherein the first tab and the second tab are longitudinally spaced apart along the planar base, and wherein the first tab is configured to extend longitudinally between the cable tray sections when the cable tray is longitudinally aligned;
- and a second splice plate comprising:
- a planar base having an interior surface and an exterior surface opposite the interior surface;
- and a first tab extending transversely from the planar base outwardly from the exterior surface;
- and a second tab extending transversely from the planar base outwardly from the exterior surface, wherein the first tab of the first splice plate overlaps the first tab of the second splice plate.
A cable tray assembly, comprising:
- a first cable tray section including a base and rails extending transversely from longitudinal sides of the base;
- a second cable tray section including a base and rails extending transversely from longitudinal sides of the base, wherein the second cable tray section is positioned adjacent the first cable tray section;
- a first splice plate coupled to first cable tray section having an interior surface facing the first cable tray section and an exterior surface opposite the interior surface and including at least first and second two tabs extending transversely from the exterior surface;
- and
- a second splice plate coupled to second first cable tray section having an interior surface facing the second cable tray section and an exterior surface opposite the interior surface and including at least first and second two tabs extending transversely from the exterior surface,
- wherein the first tabs of a first tab of the at least two tabs of the respective first and second splice plates at least partially overlap and are coupled to one another.
