Abstract: An electrical equipment cable trough system for use with electrical equipment panel installations and providing internal retaining members defining a cable way having a cable-insertion space extended between the upper and lower extremities of each panel. Additionally, U-shaped header troughs are attached to the upper extremity of each panel with U-shaped cross-troughs extending between parallel groups of abutting panels. The interrelation between adjacent header troughs and cross-troughs permit a single panel to be removed from a group while continuing to provide support for the interconnected conductors carried by the trough system.
