Fehlerstrompfadbereitschaft
Fehlerstrompfa is a German term that translates to "residual current" or "fault current." It refers to an unintended flow of electrical current through a path other than the intended circuit. This can occur due to insulation breakdown, faulty wiring, or contact with conductive materials. Residual current is a critical safety concern in electrical systems because it can lead to electric shock, fire, and damage to equipment.
Electrical safety devices like Residual Current Devices (RCDs), also known as Ground Fault Circuit Interrupters (GFCIs)
The magnitude of residual current that triggers an RCD can vary depending on the application and regional
