Wall-mounted electrical distribution boxes typically range from 200×200×120 mm to 800×600×300 mm, with materials, IP ratings, and mounting features varying by model and manufacturer.

Typical Dimensions and Sizes

Wall-mounted distribution boxes are available in a variety of sizes depending on the application. Common dimensions for residential and commercial use range from 200 × 200 × 120 mm up to 800 × 600 × 300 mm for plastic or metal enclosures . Specific product examples include:

• PCE Wall Mounted Distribution Box: 350 × 210 × 150 mm, solid rubber housing, IP54 protection .
• Metal IP65 Box: 300 × 200 × 150 mm, suitable for higher protection against dust and water ingress .

Material and Construction

• Plastic enclosures: Lightweight, durable, and often feature a hinged transparent cover for easy inspection .
• Metal enclosures: Provide higher mechanical strength and can achieve IP65 protection, suitable for harsher environments .
