Abstract

Aspects of an electrical safety device that provides detection of miswiring of line and load connection pairs are presented. In an example, the device includes a differential current detector through which are routed a live current path and a neutral current path coupling the line and load connection pairs. The device also includes a selectable conducting path that, when selected, circumvents the differential current detector while coupling one of a line live connection to a load live connection or a line neutral connection to a load neutral connection of the connection pairs. The device further includes a control circuit that determines, via the differential current detector, while the conducting path is selected, a differential current defined by a difference in currents on the live and neutral current paths, and interrupts at least one of the live and neutral current paths in response to the differential current not exceeding a threshold value.
