BP Connectors (Blue Point connectors) are screw-tightening electrical connectors used throughout Australia [ Read More ]
BP Connectors (Blue Point connectors) are screw-tightening electrical connectors used throughout Australia for joining cables in lighting and power circuits. They feature brass terminals housed in insulated plastic casings, accepting cables from 2x6mm² to 2x35mm², rated at 32-40A. Available in single-screw and double-screw versions from brands like NLS and Clipsal, they're AS/NZS 3000:2018 compliant for residential and commercial installations.
BP stands for Blue Point connector. The name comes from the original Blue Point brand that first introduced this screw-tightening connector design. Over time, electricians across Australia adopted "BP connector" as the standard name for any screw-type cable connector regardless of manufacturer. The term now covers all similar connectors including those branded as acorns or cable joiners.
BP connectors provide secure mechanical connections through screw-tightening mechanisms that clamp twisted wires together. Unlike wire nuts that rely on spring tension, BP connectors offer visual confirmation through clear housings and create gas-tight connections that resist corrosion. The brass terminals maintain low contact resistance over time, reducing heat buildup in the connection.
Single-screw connectors have one terminal with a single brass screw for joining active or neutral conductors. Double-screw connectors feature two brass screws in one terminal, traditionally used for earth connections to provide additional mechanical security. Modern standards allow single-screw earth connections if the screw occupies at least 80% of the terminal tunnel, but many electricians prefer double-screw for earth as standard practice.
All BP connectors from major brands are designed to comply with AS/NZS 3000:2018 Wiring Rules. Proper installation requires connectors to be housed in junction boxes, adequately supported, and protected from mechanical damage. Connectors must be rated appropriately for the circuit load (typically 32A minimum for power circuits, 40A for heavy-duty applications).
The 32A rating suits standard 20A lighting circuits and 25A power circuits used in residential installations. The 40A heavy-duty versions handle commercial loads and workshop equipment. The 2x6mm² capacity covers the most common Australian cable sizes (1.0mm², 1.5mm², 2.5mm² conductors). Brass terminals resist oxidation better than steel alternatives, maintaining connection integrity over decades. Clear housings allow visual inspection to verify proper wire insertion and detect corrosion without disassembly.
For Active & Neutral Connections
Features one brass terminal with single screw mechanism. Most common type for joining active and neutral conductors in lighting and power circuits. Available in standard (2x6mm²) and heavy-duty (up to 2x16mm²) versions.
Common Applications: Lighting circuits, power points, standard cable extensions
Rating: 32A standard, 40A heavy-duty
Traditionally for Earth Connections
Features two brass screws in one terminal for enhanced mechanical security. Historically required for earth connections, though modern standards permit single-screw if screw diameter exceeds 80% of tunnel diameter. Many sparkies still prefer double-screw for earth as best practice.
Common Applications: Earth connections, high-vibration environments, critical safety circuits
Rating: 32A standard, up to 40A heavy-duty
While AS/NZS 3000:2018 allows single-screw earth connections (provided screw diameter meets 80% tunnel requirement), many experienced electricians continue using double-screw connectors for earth as standard practice. This eliminates the need to verify screw-to-tunnel ratios and provides additional mechanical security. If unsure, double-screw for earth is always compliant and eliminates measurement requirements.
Installation requires twisting conductors together, inserting into the connector terminal, and tightening the brass screw until secure. All connections must be housed in approved junction boxes and adequately supported.
Strip 10-12mm of insulation from each conductor using wire strippers. For stranded cables, twist the copper strands tightly clockwise to prevent fraying. Then twist both conductor ends together clockwise to create a solid mechanical connection before inserting into the connector. The pre-twisted cables ensure maximum contact surface area within the terminal.
Loosen the brass screw inside the connector terminal (don't remove completely). Push the twisted conductors fully into the terminal opening, ensuring all bare copper enters the connector body with no exposed copper visible outside. For clear-housed connectors, visually verify that conductors reach the back of the terminal chamber.
Using a flathead screwdriver, tighten the brass screw firmly until the conductors cannot move. Apply firm pressure but avoid overtightening which can damage the brass threads or deform the terminal. The screw should be tight enough that conductors don't pull out with moderate tugging force. For double-screw connectors, tighten both screws evenly.
Place all BP connectors inside an approved junction box. AS/NZS 3000:2018 requires all cable joints to be accessible, protected from mechanical damage, and adequately supported. Secure junction box lid and label if necessary. Never leave BP connectors exposed in ceiling voids or wall cavities—they must always be housed in proper enclosures.
When working with multiple connections in one junction box, use a connector pack to ensure you have sufficient quantity and matching types. Keep single-screw and double-screw types organised in your connector jar to avoid confusion when making earth connections. Always perform a gentle tug test on each connection before closing the junction box—if conductors pull out easily, the screw isn't tight enough.
All permanent electrical work in Australia must be performed by a licensed electrician in compliance with AS/NZS 3000:2018 requirements. Isolated systems must remain de-energised during installation.
Join cables when extending lighting circuits for additional downlights, pendants, or wall lights. Single-screw connectors handle 1.0mm² and 1.5mm² lighting cables efficiently in ceiling junction boxes.
Connect 2.5mm² cable for power point extensions and additions. The 32A rating exceeds requirements for standard 20A power circuits. Use double-screw connectors for earth connections as best practice.
Join earth conductors and neutral bars when upgrading switchboards or adding circuits. Heavy-duty models like the 2x16mm double-screw connector suit larger cables in main switchboards.
Repair damaged cables by cutting out damaged sections and rejoining with BP connectors inside junction boxes. The screw mechanism creates reliable long-term connections without requiring special crimping tools.
Connect multiple lighting circuits in suspended ceiling grids. Clear housings on Clipsal BP connectors allow easy inspection without opening junction boxes during maintenance.
Modify existing circuits quickly during fit-outs and merchandising changes. BP connectors allow circuit extensions without replacing entire cable runs, reducing material costs and installation time.
Heavy-duty models like 2x35mm double-screw connectors handle large cable sizes for three-phase machinery and industrial equipment. The 40A rating suits workshop circuits with high current demands.
Create temporary power distribution for construction sites, events, or testing installations. BP connectors can be disconnected and reused when temporary power requirements change or projects complete.
AS/NZS 3000:2018 requires all BP connectors to be housed in accessible junction boxes. Junction boxes must be adequately supported, protected from mechanical damage, and positioned to remain accessible for future maintenance. Never bury BP connectors in insulation without proper enclosures—this creates fire hazards and violates Australian electrical standards. Use weatherproof junction boxes for outdoor applications and ensure all boxes are appropriately rated for their installation environment.

All BP connectors must be housed in approved junction boxes. Never leave connectors exposed in ceiling voids, wall cavities, or under insulation. Junction boxes must be positioned to remain accessible without removing permanent building elements like plasterboard or floor coverings.
Cables must be adequately supported within 150mm of the junction box using approved cable clips or saddles. This prevents mechanical stress on connections from cable weight or movement. Junction boxes themselves must be securely fixed to structural members, not suspended by cables.
BP connectors must be rated equal to or greater than the circuit's protective device rating. Use 32A minimum for standard power circuits protected by 20A or 25A breakers. Heavy-duty 40A connectors suit larger loads and commercial applications with higher current demands.
Earth conductors may use single-screw connectors if the screw diameter exceeds 80% of the terminal tunnel diameter. However, double-screw connectors eliminate the need for measurement verification and provide additional mechanical security, making them preferred for earth connections by many electricians.
Use weatherproof junction boxes with appropriate IP ratings for outdoor or damp locations. Standard plastic-housed BP connectors are suitable for dry indoor locations. For corrosive environments, consider specialist connectors with enhanced corrosion protection beyond standard brass terminals.
Junction boxes must have appropriate cable entries and glands. Ensure cables enter boxes without sharp bends that could damage insulation. Where cables pass through metal enclosures, use rubber grommets to prevent insulation damage from metal edges.
When documenting installations for compliance certification, photograph junction boxes with lids removed, showing all BP connections properly secured and labelled. This documentation helps during compliance inspections and provides a reference for future maintenance. Keep records of connector ratings, installation dates, and circuit details for all junction boxes installed during projects.
Non-compliant BP connector installations represent serious electrical hazards. Exposed connectors in ceiling voids can create fire risks when insulation contacts live parts or when connections overheat from poor terminations. Junction boxes buried under permanent building elements violate accessibility requirements and make future maintenance dangerous. Always engage licensed electricians for installation work—compliance protects lives and property values.
Decades of proven performance in Australian electrical installations. The screw-tightening mechanism creates gas-tight connections that resist corrosion and maintain low contact resistance over time. Brass terminals don't oxidise like steel alternatives, ensuring long-term reliability.
Clear plastic housings allow visual inspection of connections without disassembly. Electricians can verify proper wire insertion, check for corrosion, and identify loose connections during routine maintenance without disconnecting circuits or removing connectors.
Screw-tightening mechanism provides superior mechanical hold compared to push-in or spring-tension connectors. Once tightened, conductors won't pull out from vibration or mechanical stress. Double-screw versions offer additional security for critical earth connections.
