5 Separation distance (s)
All metallic parts building and electrically
powered equipment and their supply cables must be
integrated into the lightning protection system.

Chapter The external lightning protection system
. Metallic components with conductive
lead into the building protected, and whose dis-
tance the conductor the external lightning protec-
tion system less than one metre, must connec-
ted directly the lightning protection system. This
measure required avoid dangerous sparking
between both air-termination system and down-con-
ductor and also the metallic building parts and elec-
trical equipment.TBS

Correctly maintained separation distance (s) between down-conductor systems and roof structures
2.
The separation distance (s) does not prevent induct-
ively coupled surge voltages!
Components with direct connection lightning pro-
tection system
A separation distance does not have observed
in buildings with cross-connected, reinforced walls
and roofs with cross-connected metal facades and
metal roofs. These
include, although are not limited to, metallic railings,
doors, pipes (with non-flammable and/or explosive
content), facade elements, etc. This distance described the separation
distance (s).1.
What the separation distance?
If there adequate distance between the conduct-
or passing from the lightning current and the metallic
building parts, the risk sparking practically non-
existent
