Coupling Dowels are used to join Solid Copper Earth Rods.
Material: Phosphor Bronze
Standard: BS 7430
Commonly used in the assembly of an Earth Rod in the application of an Earth Termination Network.
An Earth Termination Network must:
- protect life,
- provide a low resistivity path to earth,
- allow circuit protection devices to operate correctly,
- carry high currents repeatedly,
- have excellent corrosion resistance properties, and
- be mechanically robust.
