Surface-mounted empty junction box PAKPLAST PO28 — electrical installation accessory, model PO28

PAKPLAST PO28 is a surface-mounted empty junction box designed for electrical installations where recessed mounting is not possible. Made as an accessory for wiring, the PO28 provides a protected enclosure for splices, terminals and cable entries in surface-mounted applications. The compact profile and neutral appearance allow it to be used for mounting switches, sockets or connecting conduits on walls and panels without structural recesses.

Advantages

The PO28 offers a simple, robust enclosure that protects electrical connections from accidental contact and dust while keeping installation accessible for maintenance. Its surface-mounted design simplifies retrofits and quick installations where chasing into walls is impractical. The box is lightweight and designed to integrate with common surface wiring components, reducing the need for custom adaptors.

Suitable for

• Surface-mounted switches and sockets installation
• Protecting wire splices and terminal connections
• Temporary or permanent surface wiring on solid walls, panels or inside utility rooms
• Connecting conduits and surface cable runs in residential and light commercial settings

When it may not be suitable

The PO28 is intended for surface-mounted applications and is not a substitute for recessed or flush-mounted boxes required by some installations or local regulations. It is not designed as a weatherproof outdoor enclosure; for exposed exterior locations or wet environments a dedicated IP-rated junction box should be used.

Key specifications

• Mounting type: surface-mounted
• Function: empty junction box for splices, terminals and cable entries
• Compatible with: surface wiring accessories such as switches, sockets and conduit connections
• Construction: single-piece enclosure with removable cover for access
• Typical applications: indoor installations, utility rooms, retrofits and surface wiring

How to use

Mount the PO28 on a clean, flat surface using appropriate screws or fasteners for the substrate. Route incoming cables through designated entry points, secure conductors with approved connectors or terminals, and close the cover to restore protection. Ensure all connections comply with local electrical codes and that the box is positioned to allow future access for inspection or maintenance.

What to consider before purchase

• Confirm that a surface-mounted junction box is acceptable for your local electrical regulations and the specific installation.
• Verify internal space is sufficient for the number and size of conductors and connectors you plan to use.
• Check material and color compatibility with surrounding fixtures and finishes.
• For outdoor or wet locations, choose an IP-rated enclosure designed for those conditions.

Usage recommendations

Install the PO28 where recessed mounting is impractical, keep cable entries tidy with suitable grommets or glands, and avoid exposure to direct moisture. Regularly inspect connections after installation and follow local electrical safety standards.
