ensure the EMC shield and personal protection, meshed equipoten- tial bonding and low-ohmic earthing system integ- rated the structure are required. 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. The earthing system part 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. 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. Whosoever causes the danger negligently, shall be liable imprisonment not exceeding three years or a fine 4.4. The equipotential bonding based the earthing sys- tem fulfils the following functions: • Protection against electric shock IEC 60364-4-41 • Protective equipotential bonding IEC 60364-5-54 • Lightning protection equipotential bonding IEC 62305 • Energy systems and surge protection IEC 60364- 4-44 • Low-voltage electrical installations IEC 60364-5- 54 • Data cabling and shielding 50310 • Electromagnetic compatibility EMC Directive 2004/108/EC (EMVG) • Antenna earthing IEC 60728 • Application equipotential bonding and earthing in buildings with information technology equipment ‒ EN 50310 • Electrical installations residential buildings DIN 18015-1 • Foundation earth electrodes‒ DIN 18014 In Germany, the foundation earth electrode new buildings must meet the requirements DIN 18014 and the technical connection conditions (TAB) the power supply generator (VNB).1." The earthing system thus represents safety-relevant part, and installation only permitted performed by an electrical lightning protection specialist. 2. addi- tion, the responsible specialist must stated the prescribed documentation. Buildings with systems and data cabling have high requirements for electromagnetic compatibility measures (EMC).4.1 IEC 60364-5-54: "For protection and function purposes, earthing systems may used together separately, according the requirements of the electrical system. It ensures operation and protects people against haz- ardous currents.2 Normative requirements The earthing system creates the electrical connection to the surrounding earth. Only electrical lightning protection specialists may install, check and accept the earthing system. Con- struction companies must allow the supervision the installation and acceptance the earthing system by electrical and lightning protection specialists. The following infringements the rules technology are specified 319 "Causing danger during con- struction work" the German Criminal Code: 1.

The protection requirements must always have priority. 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.1 Basic principles The earthing system the basis for the safe function of every electrical system and its protection devices
