Why Choose the ABB JCH2708 Test Coupling?
The ABB JCH2708 (2CTH0JCH2708) is a purpose-designed test coupling / test joint for external lightning protection systems. Installed in the down-conductor path, it enables the conductors to be disconnected when carrying out insulation and earthing measurements, providing an accessible test point for inspection and maintenance of the lightning protection installation.
Manufactured from die-cast brass, the JCH2708 is designed to provide excellent electrical conductivity with low impedance. Its clamping arrangement eliminates the need to drill the conductors during installation and accommodates both round and flat conductor formats commonly used in external lightning protection systems.
The JCH2708 accepts 6 mm and 8 mm diameter round conductors as well as 30 × 2 mm and 30 × 3 mm flat conductors. The unit measures 70 × 50 × 20 mm, weighs approximately 0.390 kg and is designed in accordance with NF C 17-102.

Reliable Test Access for Lightning Protection Systems
Periodic inspection and testing are important parts of maintaining an external lightning protection system. A test coupling provides a deliberate point at which the down conductor can be disconnected from the earth termination system, allowing insulation and earthing measurements to be performed without permanently altering the conductor installation.
The ABB JCH2708 provides this function while maintaining a conductive, low-impedance connection during normal service. Its compatibility with multiple round and flat conductor sizes makes it suitable for a range of lightning protection configurations. During installation, the connected down conductors should overlap over the full height of the test joint.
Typical Applications
- External lightning protection systems.
- Lightning protection down-conductor test points.
- Earth termination system inspection and testing.
- Commercial and industrial building lightning protection.
- Infrastructure and utility installations.
- Lightning protection systems requiring periodic earthing measurements.
