A light for an industrial stringlight includes a cap having wire channels receiving insulated conductors. Non-interchangeable contact elements are placed in a screw-shell adapted to hold a lamp, and the cap and screw-shell are forced together. The cap is secured to the screw-shell, and insulation-piercing points on the contact elements establish electrical continuity with their associated conductors. The assembly is then overmolded for protection and sealing. A lamp guard is assembled to the overmold and has a bottom section hinged about a horizontal axis to permit replacing the lamp from beneath.

Industrial molded stringlight

An electrical wiring device designed to be attachable to a cable in the field includes a housing which receives a core. Electrical contact elements (male or female) are carried by the core. At the rear of the housing, in an extension which receives the cable. The extension includes a series of spaced, truncated walls are formed in opposing relation to similar truncated walls formed in the clamp member. When the clamp is assembled to the housing extension, each pair of opposing truncated walls defines a cable-receiving aperture which is sized to clamp to a given range of cable sizes for strain relief. By reversing the clamp, the clamp-receiving apertures clamp to a different range of cable sizes while providing strain relief for the connections. The clamp also secures the core to the housing in either position of attachment.
