Hubbell Incorporated Raco Wire Cap Connector 4803-5

Wire Cap Connector for 0.50–0.63 in Cords

The Hubbell Incorporated Raco 4803-5 is a straight aluminium cord connector that accepts a single cable with an outside diameter between 0.50 in and 0.63 in. It threads into a 3/4 in MNPT box opening and is rated to UL 514B for use in electrical installations. The brown gland colour code identifies the cable range at a glance.

Sustained Load Behaviour

The aluminium body and gland resist corrosion and mechanical stress during continuous operation in damp or industrial environments. With no external strain relief fitted, the connector relies on the internal gland compression to hold the cord securely against vibration and thermal cycling. The insulated construction is absent, so the metal shell remains conductive and must be bonded to the grounding system.

Build Quality and Mounting Implications

The silver aluminium finish provides a durable surface that withstands handling and exposure to oils or solvents common in maintenance areas. A 9/16 in length from the box face to the connector end keeps the profile compact inside enclosures or junction boxes. Installers should verify the 3/4 in MNPT thread matches the enclosure entry before committing to the installation.
