Abstract: Power distribution systems and methods are described. In one example, a method of testing a power distribution system including a first circuit protection device and a second circuit protection device coupled to the first circuit protection device downstream of the first circuit protection device is described. The method includes monitoring a status of a communicative connection between a ZSI output port of the first circuit protection device and a ZSI input port of the second circuit protection device with a ZSI monitor of the first circuit protection device, detecting whether the ZSI output port of the first circuit protection device is coupled to the ZSI input port of the second circuit protection device, and indicating the status of the communicative connection.

Abstract: A fault detection/alarm system includes an oscillator at one end of a signal cable whose clock output is OR'ed with a fault detection signal. A receiving unit receives the OR'ed signal and detects the leading edge of the clock. If the clock signal disappears due to breakage of the signal cable, the appearance of a fault detection signal or other reason, the leading edges are no longer detected, causing the raising of a fault signal which may be an emergency stop signal for the receiving unit.
