Patent ID: 7096165

Claim:
A method for configuring an electrical installation having a network which extends from a feed side to a load side, comprising: determining a network map by at least one of, determining a feed circuit based upon presets for at least one electrical device, available power and circuit length, and determining a load circuit based upon presets for an intended load and the circuit length, and determining a load circuit based upon presets for an intended load and the circuit length, determining a feed circuit based upon the circuit length, and using the results from algorithms and the presets for the load circuit, wherein the feed circuit and the load circuit are coupled to a virtual interface, wherein the following steps are carried out for each circuit, and for at least one of parallel branches in the feed circuit and in the load circuit, based on the sum of the loads as far as the circuit under consideration: a) determining at least one of devices and protective measures for obtaining overload safety on the basis of the total load and predetermined tables and algorithms, and on the basis of selection tables for establishing suitable appliances; b) determining at least one of devices and protective measures for obtaining short-circuit protection for short-circuit currents which are obtained on the basis of algorithms from the results according to a); c) determining at least one of devices and measures for protection of life against electric shocks in the case of indirect contact, on the basis of the results from a) and b) and on the basis of tables and/or of algorithms, d) determining at least one of power cross section and of parallel conductors on the basis of the assessment of cable lengths on the basis of the results according to a) to c) from a cable point under consideration to a load under consideration using the consideration measure that a voltage for correct operation of the load is present across the load, on the basis of the voltage drop, e) determining, for the situation where two or more protective devices are provided in series, devices which have a selective response with respect to one another, on the basis of the results according to a) to d) and on the basis of selection tables, if the protective switching devices have not satisfied the selectivity requirements, f) producing the network map on the basis of the accumulated results according to a) to e).
