6.7 Finding breaks in the loop wire

Breaks in the loop wire are usually the result of
unintentional physical damage to the wire such
as when gardening with a shovel. In countries
with ground frost, also sharp stones that move in
the ground can damage the wire. Breaks can
also occur due to the wire being stretched
excessively during installation.
