Abstract: An arc fault detection system includes a high frequency detector module structured to detect first spectral content of power having a frequency in a first frequency range, a number of arc fault circuit interrupters each having separable contacts, a low frequency detector module structured to detect second spectral content of power having a frequency in a second frequency range, a control unit structured to control the separable contacts to trip open, and an arc fault detection unit structured to detect an arc fault based on the detected first and second spectral content of the power and to cause the control unit to control the separable contacts to trip open in response to detecting the arc fault. A communication bus provides communication between the high frequency detector and the arc fault circuit interrupters and the first frequency range includes frequencies that are higher than frequencies in the second frequency range.
