The earthing terminal AM9 is mainly used to connect earthing conductors to various kinds of pipework, in sizes Ø 6-15 mm. The earthing terminal can also be used to connect earthing conductors to a building’s concrete reinforcement. A suitable concrete reinforcement bar has a diameter of between 8-15 mm. The earthing conductor has one 4-35 mm² strap. If there is a need for a 25 mm² copper connector, two AM9 terminals must be used in parallel. The conductor bar is made of tinned copper and the strap is made of zinc-plated, yellow-passivated steel.
