addi-
tion, the responsible specialist must stated the
prescribed documentation.2 Normative requirements
The earthing system creates the electrical connection
to the surrounding earth. It
ensures operation and protects people against haz-
ardous currents. The protection requirements
must always have priority.
Only electrical lightning protection specialists may
install, check and accept the earthing system. Whosoever, cases under subsections (1) and (2)
above, acts negligently and causes the danger neg-
ligently shall liable imprisonment not exceed-
ing two years fine.
The following infringements the rules technology
are specified 319 "Causing danger during con-
struction work" the German Criminal Code:
1. Whosoever, engaging profession trade, vi-
olates generally accepted engineering standards in
the planning, management execution project
to install technical fixtures structure modi-
fy installed fixtures this nature and thereby en-
dangers the life limb another person shall in-
cur the same penalty.
2. ensure the EMC
shield and personal protection, meshed equipoten-
tial bonding and low-ohmic earthing system integ-
rated the structure are required.1 IEC 60364-5-54: "For protection
and function purposes, earthing systems may used
together separately, according the requirements
of the electrical system. The earthing resistance of
the system should small possible (less than
10 and must coordinated with further protective
measures and switch-off conditions."
The earthing system thus represents safety-relevant
part, and installation only permitted performed by
an electrical lightning protection specialist.
The earthing system part the electrical system.1.
2. Whosoever, the planning, management execu-
tion the construction the demolition struc-
ture, violates generally accepted engineering stand-
ards and thereby endangers the life limb an-
other person shall liable imprisonment not ex-
ceeding five years fine.
Note
Section 542. Buildings with systems and data
cabling have high requirements for electromagnetic
compatibility measures (EMC).4.
3. Whosoever causes the danger negligently, shall be
liable imprisonment not exceeding three years or
a fine
4.1 Basic principles
The earthing system the basis for the safe function
of every electrical system and its protection devices.
