Electrical installation arrangement

An electrical installation arrangement for the operation of an electrical consumer network, comprising:

• at least one first switch for the predeterminable disconnection of at least one first consumer and/or a partial network from the consumer network,
• at least one first arc detector, comprising at least one first sensor for measuring at least one first electrical parameter in the consumer network and for the output of a first measuring signal, with the arc detector further comprising an analysis unit for the analysis and/or evaluation of the first measuring signal as a result of at least one first analytical and/or evaluation scheme for recognizing an arc or at least an electrical effect of the arc on the electrical consumer network,
• at least one first tripping unit, which upon detection of an arc by the arc detector switches off the first switch and thereby disconnects the consumer and/or the partial network from the consumer network,
• wherein a second analytical and/or evaluation scheme is provided,
• wherein the first analytical and/or evaluation scheme has a higher sensitivity than the second analytical and/or evaluation scheme,
• wherein the second analytical and/or evaluation scheme is provided in the presence of a first living being of a predeterminable type in a predeterminable first surrounding area around the first consumer and/or the partial network, and
• wherein the first analytical and/or evaluation scheme is provided in the absence of the first living being in the first surrounding area.
