Earthing materials

Earthing products are made tough and durable to guarantee
reliable earthing and to complete safe electrical installation
in a building.

The AM8 earthing terminal is mainly
used for connecting the earthing
conductors to various pipework. Due
to the structure of the terminal, it is
possible to adjust it to suit to four
different pipe thicknesses between 8
to 28 mm. The terminal has two 35
mm² pillar terminals. The conductor
bar is made of tinned copper and the
strap of zinc-plated steel.

The AM11 earthing terminal is used, for example, for the potential
equalization of air-conditioning and ventilation ducts. The earthing
terminal is affixed using two pull rivets (pop-rivets) c/c 3,2 mm to the
surface of the duct. The terminal bar is made of tinned copper and has
a single <10 mm² Cu terminal.

The earthing terminal AM9 is mainly used to connect earthing
conductors to various kinds of pipework in sizes c/c 6-15 mm. The
earthing conductor has one 4-35 mm² strap. The earthing terminal can
also be used to connect earthing conductors to a building’s concrete
reinforcement - protective gap must be used. The conductor bar is
made of tinned copper and the strap is made of zinc-plated, yellow-
passivated steel.
The potential equalizer bars AM4 and AM5 are intended for the
connection of system earthing conductors in buildings. Into AM4 it is
possible to connect 8 pcs of max. 50 mm² and 2 pcs of max. 70 mm²
conductors. into AM5 it is possible to connect 5 pcs of max. 50 mm²
conductors. Both bars are made of tinned copper. If necessary, the bars
can be covered with protective housing PMR576.
