An electrical device for connecting to an electrical distribution network of a building. The electrical distribution network is connected to an electrical energy supply network. The electrical device has a switching device for switching on and off an electrical load. For the purpose of relatively simple demand control of the electrical load, the electrical device has a monitoring device for monitoring the voltage and/or frequency at the electrical device on the distribution network side and to generate a switch-on signal if the monitored voltage and/or frequency exceeds an upper threshold value and to generate a switch-off signal if the monitored voltage and/or frequency falls below a lower threshold value. The switching device establishes a current flow between the distribution network and the electrical load when a switch-on signal is present and interrupts a current flow between the distribution network and the electrical load if a switch-off signal is present.
