Where the AB443C Adaptable Box Fits

An adaptable box provides a weatherproof, accessible enclosure at any point in an electrical installation where cables need to be joined, terminated, or transitioned — particularly in outdoor, exposed, or conduit-wired locations where a standard TPS junction box would not provide adequate weather protection. The AB443C is sized for installations requiring more internal space than a smaller adaptable box — the 108 x 108mm footprint and 76mm depth accommodate multiple cable terminations, terminal blocks, or small wiring accessories within the one enclosure.

The pre-scored knockouts on all four sides and the base allow the conduit entries to be positioned exactly where the conduit runs require — simply punch out the knockout at the required position and fit the appropriate conduit adaptor or gland. Unused knockout positions remain sealed, maintaining the IP66/IP55 ingress protection rating. The removable lid provides full access to the interior for wiring, inspection, and future modifications without disturbing the conduit system.

Typical applications include outdoor cable junction points for power and lighting circuits, weatherproof enclosure for isolators and switching accessories, conduit system junction points where multiple conduit runs converge, and any installation requiring a square weatherproof enclosure at an accessible height on an external wall, post, or structure.

The Rylec AB range covers five sizes from 77x77x54mm through to 380x300x120mm — all grey PVC, IP66/IP55 rated, with knockout conduit entries.

Q: What is the difference between an adaptable box and a junction box?
A: An adaptable box (AB443C) is a heavy-duty weatherproof PVC enclosure with removable lid and pre-scored knockout conduit entries on all sides — designed for conduit-wired systems in exposed or outdoor locations with high IP protection. A standard junction box (e.g. JB-series conduit junction boxes) is typically designed for a fixed number of conduit entries in a specific configuration. The adaptable box is more flexible in conduit entry positioning and provides higher weather protection.

Q: What do the IP66 and IP55 ratings mean for the AB443C?
A: IP66 means the enclosure is dust-tight (6) and protected against powerful water jets from any direction (6). IP55 means protected against dust ingress sufficient to prevent harmful deposits (5) and protected against water jets from any direction (5). The dual rating IP66/IP55 indicates the box achieves IP66 when the lid is fully closed and sealed, and IP55 in normal operating orientation. Both ratings make the AB443C suitable for outdoor and exposed electrical installations.

Q: What size conduit entries does the AB443C accept?
A: The conduit entry size depends on the knockout diameter and the conduit gland or adaptor fitted. Confirm the knockout dimensions against your conduit size requirement before installation. Standard conduit glands and adaptors in 20mm and 25mm are the most common sizes used with adaptable boxes of this footprint.
