EARTHING MATERIALS 77
The earthing strap PP36 (strap clamp AM2 and
terminal AM3) is for earthing heavy-duty
pipework. The strap is 1 meter long, and it is
made of tinned annealed copper 1,5 mm thick.
The Cu-conductor of max. 35 mm² is connected
using the earthing terminal AM3. In case a 50 mm²
or 70 mm² Cu-conductor is connected to the
earthing block, both ends of the earthing strap
must be pressed together with the terminal to
get sufficient conductivity. The terminals and the
strap clamp are made of zinc-plated and yellow-
passivated steel.
