Home / What is the depth of a standard electrical distribution box
Are plastic and metal electrical box dimensions the same? The face dimensions are often similar, but internal volume and depth options can differ. This guide will explore the different electrical box depth options, including 1", 2", and deep types, and explain how depth affects your installation. While the height and width are standardized to accommodate universal switches and receptacles, the depth varies based on the volume required for wire. Typical wall-mount enclosure sizes often range from about 200 × 200 × 120 mm up to 800 × 600 × 300 mm. Freestanding cabinets commonly range from about 1600–2200 mm in height, 600–1800 mm in width, and 300–600 mm in depth.
