Earthing – Single-family house without external lightning protection

Whether existing or new buildings, a functioning earth-termination system is the prerequisite for the safe operation of electric systems in buildings and for protecting people from dangerous high voltages.

The design and implementation of the earth-termination system are of central importance. When implementing the earthing concept, e.g. in the form of a foundation earth electrode, changes are no longer possible after the concrete has set. Omissions or errors during the construction phase cannot be corrected later or, at least, not without a great deal of effort and expense.
