In order achieve clean insertion, the use strip

Connection lugs
Connection lugs must made materials with per-
manent corrosion protection. Either hot galvanised
steels with plastic jacketing rustproof stainless
steels with molybdenum content must be
used, e.4.
Materials for ring earthers
The following materials can used for the grid ring
earther:
• Stainless steel flat conductors, 3. The connection lugs
should clearly marked with protective caps during
the construction phase, e.5 mm
• Stainless steel flat conductors, 3.4.
This grid ring earther must connected with the
functional equipotential bonding conductor and must
be executed follows either outside within the
floor plate:
• Grid width with lightning protection
measures
• Grid width without lightning protection
measures
Materials for foundation earthers and functional
equipotential bonding conductors
The following materials can used, amongst others:
• Galvanised steel flat conductors, 3.4. 5018 for marking
