## Summary description

ALPAR G40 is a 4-screw cross connector designed for lightning protection and earthing installations. It provides a secure mechanical and electrical connection between conductors at a cross junction using four fastening points. Suitable for bonding multiple conductors in external lightning down-conductor networks and earthing systems where reliable continuity and corrosion-resistant contact are required.

## Long description

ALPAR lightning protection cross connector 4-screw model G40 is a mechanical and electrical connector designed for use in external lightning protection and earthing networks. The connector provides a four-point fastening arrangement that secures and bonds multiple conductors at a cross junction, ensuring reliable continuity of the lightning down-conductor or earthing conductors while offering corrosion-resistant contact suitable for outdoor installations.
Advantages
The connector’s four-screw design delivers uniform pressure across conductors, improving mechanical stability and low-resistance electrical contact. Constructed from materials suitable for outdoor use, it resists corrosion and maintains conductivity over time. Its compact cross shape allows neat routing of intersecting conductors and simplifies installation at junctions without the need for specialized tools beyond standard hand tools.
Suitable for
 Bonding multiple lightning down-conductors at a cross junction
 Connecting earthing conductors in external grounding systems
 Field installations where corrosion-resistant, durable connections are required
 Retrofit or new-build lightning protection networks
When it may not be suitable
This connector is intended for use with conductors and environments typical of lightning protection and earthing systems; it may not be appropriate for fine-stranded flexible conductors that require specialized clamps, for conductors above the connector's mechanical capacity, or for applications demanding insulated or sealed joints. For buried or fully submerged connections, a dedicated sealed connector designed specifically for such conditions should be used.
Key specifications
 Type of connection: four-screw cross junction for conductor bonding
 Application: external lightning protection and earthing systems
 Contact: corrosion-resistant conductive materials suitable for outdoor exposure
 Mechanical fastening: four threaded screw clamps for secure conductor retention
 Mounting: inline cross configuration for intersecting conductors
How to use
Position the cross connector at the intended junction point and insert each conductor into its respective channel. Tighten each screw progressively and evenly to achieve uniform clamping pressure and secure electrical contact. Ensure conductor surfaces are clean and free of paint or heavy oxidation before making the connection. After tightening, verify mechanical stability and continuity with appropriate testing equipment according to applicable standards and local regulations.
What to consider before purchase
 Compatibility with conductor sizes and types used in your lightning or earthing system
 Environmental exposure and whether additional corrosion protection or sealing is required
 Mechanical capacity for tension, wind load, or other site-specific forces
 Compliance with local lightning protection and electrical earthing standards
Usage recommendations
Use standard torque values recommended for similar screw-type connectors and recheck tightness after initial thermal cycling. Inspect connections periodically for corrosion or loosened screws and replace the connector if signs of degradation appear.
