2. This means
that the potential connection can made via metallic
and earthed roof structures, generally earthed parts of
the building structure and via the protective conductor
of the low-voltage system.
The insulated air-termination rod should connected
to reference potential using mm² equal
conductivity. These val-
ues should compared with those Tables 2.17: Concrete blocks for insulated air-termination rods
