Abstract
Power distribution systems and methods in which a power distribution unit (PDU) is provided with residual current monitoring at multiple outlets of an outlet module in a PDU. A residual current monitoring circuit of the PDU includes at least one current sensor associated with the outlets of the PDU to detect residual current for each of the outlets. The methods of residual current detection in a PDU having multiple power outlets includes detecting current leakage at each outlet as a difference between supplied current and return current for each outlet.
