The SOUTHWIRE G603-UPC is a 1-gang steel welded conduit wall box designed for mounting toggle switches, duplex receptacles, and decorative wiring devices in conduit-fed electrical installations. Constructed from welded steel, this deep switch box provides a secure, rigid enclosure suitable for both residential and light commercial work. The gangable design allows installers to join multiple boxes side by side when a multi-device configuration is required. UL listed and RoHS compliant, the G603-UPC meets standard safety and environmental requirements for electrical enclosures.
This box is used in conduit wall installations where a single-gang device box is required. Typical applications include switch and receptacle rough-in work in new construction or renovation projects. The gangable construction is especially useful when consolidating multiple controls or outlets at a single wall location. Electricians working under NEC guidelines will find this box compatible with standard conduit entry configurations for indoor wiring applications.
Designed as an OEM-style replacement and standard-fit conduit wall box for 1-gang electrical device installations using rigid or EMT conduit systems.
Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize the circuit at the panel before beginning any rough-in or device mounting work. Secure the box firmly to framing or structural support before pulling conductors. Verify conduit knockouts align with your raceway entry points before finalizing the box position.
