Why Choose the ABB Equipotential Connection Box?
The ABB Equipotential Connection Box is a dedicated earth coupling accessory for external lightning protection systems, designed to provide an accessible connection between the lightning earth termination system and the building's earth loop. Installed at the bottom of the lightning down conductor, it allows the two earthing systems to be conveniently interconnected or disconnected when required.
The ABB BLH2707 uses a copper connection bar mounted on two insulators, protected by a galvanised steel cover. The copper bar provides connection points for two conductors, creating a robust and accessible equipotential bonding point within the external lightning protection installation.
With dimensions of 150 × 65 × 65 mm and a unit weight of 0.550 kg, the box is compact enough for installation close to the base of the down conductor. It is supplied complete with wood-screw brackets and earth identification labels and is supplied under ABB order code 2CTH0BLH2707.

Accessible Equipotential Bonding for Lightning Earthing Systems
Equipotential bonding is an important part of a coordinated lightning protection installation. The ABB BLH2707 provides an accessible location where the lightning earth termination system can be interconnected with the building's earth loop. Its copper bar accepts two conductors and is electrically supported on two insulators inside a protective galvanised steel enclosure.
The ability to disconnect the interconnection also supports inspection and maintenance activities where separation of the lightning earth termination system and building earthing network is required. The box should be installed at the bottom of the down conductor as part of the complete lightning protection and earthing design, with conductor selection, bonding and earth termination arrangements determined by the applicable installation requirements.
Typical Applications
- Equipotential bonding in external lightning protection systems.
- Connection between lightning earth termination systems and building earth loops.
- Lightning down-conductor earthing installations.
- ABB OPR external lightning protection systems.
- Commercial and industrial buildings.
- Manufacturing facilities and warehouses.
- Infrastructure and utility installations.
- Lightning protection systems requiring an accessible, disconnectable earth interconnection point.
