An electrical safety device (100, 200) comprising: a live current path coupling a line live connection and a load live connection; a neutral current path coupling a line neutral connection and a load neutral connection; a differential current detector through which the live current path and the neutral current path are routed; a selectable conducting path that, when selected, circumvents the differential current detector while shorting one of the line live connection to the load live connection or shorting the line neutral connection to the load neutral connection; a control circuit (104, 204) to: select the selectable conducting path; determine, via the differential current detector, while the selectable conducting path is selected, a differential current defined by a difference between a first current on the live current path and a second current on the neutral current path; and interrupt at least one of the live current path and the neutral current path in response to the differential current not exceeding a threshold value; characterised by a load circuit coupled between the live current path and the neutral current path to provide an electrical load in response to a first control signal; wherein the control circuit (104, 204) is to provide the first control signal to the load circuit while the selectable conducting path couples one of the line live connection to the load live connection or the line neutral connection to the load neutral connection. a live current path coupling a line live connection and a load live connection; a neutral current path coupling a line neutral connection and a load neutral connection; a differential current detector through which the live current path and the neutral current path are routed; a selectable conducting path that, when selected, circumvents the differential current detector while shorting one of the line live connection to the load live connection or shorting the line neutral connection to the load neutral connection; a control circuit (104, 204) to: select the selectable conducting path; determine, via the differential current detector, while the selectable conducting path is selected, a differential current defined by a difference between a first current on the live current path and a second current on the neutral current path; and interrupt at least one of the live current path and the neutral current path in response to the differential current not exceeding a threshold value; select the selectable conducting path; determine, via the differential current detector, while the selectable conducting path is selected, a differential current defined by a difference between a first current on the live current path and a second current on the neutral current path; and interrupt at least one of the live current path and the neutral current path in response to the differential current not exceeding a threshold value; characterised by a load circuit coupled between the live current path and the neutral current path to provide an electrical load in response to a first control signal; wherein the control circuit (104, 204) is to provide the first control signal to the load circuit while the selectable conducting path couples one of the line live connection to the load live connection or the line neutral connection to the load neutral connection.
