An integrated protection system for an electrical distribution system including a panelboard for receiving power from a utility source and distributing the power to a plurality of branch circuits each having line and neutral conductors for delivering the power to a load. The integrated protection system comprises a plurality of arcing-fault detectors and line interrupters attached to positions in the panelboard. The arcing-fault detectors detect the occurrence of an arcing fault in either of the branch circuits, while the line interrupters disconnect the load from the power source in response to the detection of an arcing fault in either of the branch circuits. The line interrupters and arcing-fault detectors may comprise separate modules, each being connected to one of the positions in panelboard or-being attached externally to the other module. Alternatively, the line interrupters and arcing-fault detectors may be combined within individual modules, each individual module being connected to a position in the panelboard. An isolation module may be attached to one of the positions in the panelboard for electrically isolating arcing- fault signals to the branch circuit on which they occur.
