The WIREMOLD G20GB512 is a gray, 3-wire, 1-circuit surface-mount raceway designed to route and protect electrical wiring along walls and ceilings in commercial and residential settings. Measuring 60.5 inches in length, 3 inches wide, and 1.5 inches deep, this raceway provides a clean, code-compliant pathway for branch circuit conductors without the need for in-wall rough-in work. At 2.93 pounds, the unit is manageable for single-person installation. Electricians and facilities maintenance technicians use this product to add or extend electrical circuits where cutting into existing walls is impractical or cost-prohibitive.
This raceway is suited for retrofit electrical work in light commercial buildings, offices, retail spaces, and institutional facilities. It supports a single circuit with a 3-wire conductor configuration, making it appropriate for standard 120-volt or 240-volt branch circuit extensions. Typical applications include adding outlets along workbench runs, extending power to modular workstations, or re-routing exposed wiring after tenant improvements.
Designed as an OEM-style surface raceway component compatible with the WIREMOLD G2000 series raceway system for 3-wire, 1-circuit branch circuit applications.
Installation is typically performed by a licensed electrician in accordance with NEC Article 386, which governs surface metal raceways. De-energize the branch circuit at the panel before making any connections. Raceway sections are mechanically fastened to the wall or ceiling substrate before conductors are pulled through. Do not exceed the raceway fill capacity as defined by the NEC for the conductor size and insulation type being used.
