A smart receptacle (2;40;80) is for a number of loads (4). The smart receptacle includes separable contacts (6); an operating mechanism (8) structured to open and close the separable contacts; and a number of current sensors (12) structured to sense current flowing through the separable contacts to one of the number of loads. A number of indicators (18,20) indicate a relative level of the sensed current or corresponding energy. A processor (22) inputs (134) the sensed current, determines (136,144) the relative level of the sensed current or the corresponding energy, and controls (142,148,152) the number of indicators to indicate the relative level of the sensed current or the corresponding energy. |
