        Clipsal by Schneider Electric | Large Junction Box 40Amp 250V | White PVC

        The Clipsal 554C4-WE is a junction box rated for 40 amp circuits at 250V, designed to house stripped cable joins in a protected enclosure. The 554C4-WE comes complete with four cable connectors and fixing nails, ready for joining multiple building wires inside walls. It complies with electrical installation standards for domestic and commercial wiring systems.

        Junction box joins are necessary when running cable through walls or conduit. Multiple cables need space to strip and terminate properly, and a crowded or under-sized box creates fire risk and fails inspection. The Clipsal large box dimensions (86mm long, 58mm wide, 45mm high) accommodate three or more cable joins comfortably, offering working room that smaller boxes cannot provide.

        Sparkies stock junction boxes as a staple on every job because they speed up cable runs and eliminate the need for in-wall splicing without protection. The 554C4-WE comes fully equipped with connectors and fixing nails, so there are no surprise gaps in materials when opening the box on site. The box fits standard wall depths, integrates with Clipsal ranges, and the PVC material resists corrosion in damp internal locations where cable joins sit for years.

        Features

        • 40 amp rated junction box — suitable for circuits up to 40 amps at 250V AC, covering most domestic and light commercial cable joining requirements.
        • Contains four cable connectors — supplied with 3 x single-screw connectors and 1 x double-screw connector, reducing the need to source additional parts on the job.
        • Supplied with fixing nails — two nails included, eliminating the need to source fasteners separately for wall mounting.
        • PVC construction — durable plastic body resists moisture and corrosion, suitable for internal dry and damp locations (not external or submersible).
        • Large internal volume — 86mm length provides ample space for three or more cable joins with room to work, eliminating the cramped conditions of smaller boxes.
        • Rectangular shape — fits standard wall box opening dimensions, compatible with existing switchboard and conduit layouts.
        • Single-piece design — clip-on lid secures the box without requiring additional clips or braces, reducing installation time.
        • 250V insulation rating — rated to 250V AC, compliant with domestic single-phase power wiring in Australia.
        • Neutral joining — supports termination of active, neutral, and earth conductors without segregation, standard for domestic wiring runs.
        • Interior joining only — designed for walls, cavities, and conduit; not rated for external, damp-exposed, or underground installations.

        Where to use

        • Domestic wall runs — joining two or three cables inside partition walls where a larger enclosure is needed to meet fire and electrical safety standards.
        • New-build and renovation wiring — bundling cable runs in new walls or extensions where multiple circuits need to join at a single point.
        • Kitchen and laundry rewires — supporting high-load circuits for cooking, heating, and appliance upgrades where cable joins must be housed in protected boxes.
        • Power and lighting circuits — joining sub-circuit cables before they run into individual protection on the switchboard.
        • Conduit entry points — protecting cable joins at the point where conduit terminates and cable transitions to in-wall wiring.
        • Ceiling and roof cavities — joining cables in accessible roof spaces where moisture and temperature fluctuations are moderate.

        The Clipsal 554C4-WE is not suitable for external walls, damp exposed locations, underground or submersible installations, or areas subject to water splash or rain exposure. It is an interior dry-location product only and must not be used outdoors or in bathrooms, laundries, or other wet areas.

        Verified Sparky Direct customer reviews: Large Junction Box 40Amp 250V (554C4-WE)

        "They are quick, cheap and easy to use" — Rod

        (554C4-WE)

        A junction box protects cable joins (where building wires are stripped and terminated together) inside walls and cavities. You need one whenever two or more cables run together and their joins must be safe from mechanical damage, safe from moisture, and accessible for future inspection. Joins cannot be buried in a wall without a box.

        No. Electrical standards require all cable joins to be housed in an approved accessible enclosure. Direct burial of joins in plaster or cavities is a safety breach and will fail building inspection. Always use a junction box.

        The 554C4-WE is a large box (86mm x 58mm x 45mm). It suits three or more cable joins because the internal space allows room to strip cable, position connectors, and pass inspection without crowding. Smaller boxes force connectors to sit tightly together, risking damage during installation and limiting the number of cables you can accommodate.

        The 554C4-WE includes 3 x single-screw connectors and 1 x double-screw connector, plus 2 fixing nails. No additional connectors are needed for a standard three-cable join. If you need more connectors, you can purchase them separately from Sparky Direct.

        The large box size suits most standard domestic cable sizes (1.5mm² to 4mm² building wire is common). The single-screw connectors clamp cable diameters up to around 4mm² in single-core or twin-and-earth configurations. Check your cable diameter against the connector specifications if you're joining larger cable.

        No. The 554C4-WE is an interior dry-location product only. It is suitable for internal dry walls, cavities, and conduit. Do not use it in bathrooms, laundries, kitchens (splash zones), external walls, or any location subject to moisture or water exposure.

        The fact that you can go on line to Sparkydirect and purchase what you need for a job and not having to go in to town which is a hour drive there and back is great for me. They are quick, cheap and easy to use I recommend them to anyone.
