Description

The Knightsbridge 100A 5-way single pole connector block is a green polycarbonate enclosure designed for earth circuit distribution in consumer units and electrical sub-boards. The block accepts up to five incoming or outgoing conductors ranging from 2.5mm² to 35mm² cross-section, with each terminal secured by an Allen key screw to maintain firm contact under load.

Used in residential, commercial and light industrial installations where a single earth conductor needs to be split into multiple outgoing earth connections, the block carries a 100A current rating on 230V AC. The IP2XD rating means the terminals are protected against insertion of a 12.5mm diameter test probe, meeting requirements for finger-safe installation in accessible locations. Unused terminal apertures are covered by internal shutters to prevent accidental contact.

The block measures 64mm tall by 51mm wide by 41mm deep, allowing it to fit within standard consumer unit enclosures with adequate clearance. Multiple blocks can be interlocked side-by-side using the moulded clips on each side, creating larger earth bar assemblies without additional fixing hardware. The green polycarbonate body provides visual identification of earth connections to aid compliance with BS 7671 wiring regulations.

Frequently Asked

What cable sizes does this accept?

The block accepts conductors from 2.5mm² to 35mm² cross-section. This covers standard domestic twin-and-earth tails (6mm², 10mm², 16mm²) and larger commercial singles up to 35mm².

Is it suitable for consumer unit installation?

Yes. The 64mm x 51mm x 41mm dimensions fit within standard UK consumer unit enclosures. The IP2XD rating meets BS 7671 requirements for finger-safe terminal protection in accessible locations.

Can multiple blocks be joined together?

Yes. The moulded interlocking clips on each side allow multiple blocks to be joined side-by-side, creating a larger earth bar assembly without needing separate mounting hardware.

What tool is needed to tighten the terminals?

An Allen key (hex key) is required to secure the terminal screws. The size is typically 3mm or 4mm — check the product specification sheet for confirmation.
