摘要： The present disclosure relates to a circuit breaker terminal box having a leakage current blocking function, in which a current leaking from both an input side and an output side of an earth leakage circuit breaker may be limited by expanding areas of a neutral line input terminal and a neutral line output terminal on both the input side and the output side of the earth leakage circuit breaker, and thus the risk of electric shock to the human body due to the leakage current can be minimized.

摘要： A supply system for supplying energy in an aircraft includes at least one electrical line including at least one core connectable to a pole of a current source, an electrically conductive shield, and a detection unit having at least two electrical inputs. The shield surrounds the at least one core under a distance and creates an intermediate space between the at least one core and the shield. At least one port of the detection unit is connected to the at least one core. At least another port of the detection unit is connected to at least one of the shield and the at least one core. The detection unit is adapted for detecting a differential current over the at least one core or an absolute current between the shield and a ground potential for generating a warning signal if a predetermined threshold value for the detected current value is exceeded.
