1. Arrangement for carrying out work on an electrical installation by a person, wherein the electrical system comprises:
a plurality of electrical circuits each with a switch configured and arranged for switching off the associated circuit of the plurality of electrical circuits,
a safety module including an emergency signal input, and the safety module is configured and arranged to
switch off a first circuit of the plurality of electrical circuits via the associated switch when an external emergency signal is received via the emergency signal input and
at least one further circuit of the plurality of electrical circuits is switched off via an associated switch, when the safety module continues to receive the emergency signal at the emergency signal input after a predetermined period of time; and
a protective device configured and arranged to be worn by the person and for detecting an electrical body current which, in the event that an unacceptable body current is detected, generates the emergency signal and transmits said signal to the emergency signal input of the safety module.
