jordfejlstrømsafbryder
A jordfejlstrømsafbryder, often abbreviated as RCD (Residual Current Device) or GFCI (Ground Fault Circuit Interrupter) in English, is a safety device used in electrical installations. Its primary function is to protect individuals from electric shock and to prevent fires caused by electrical faults. It works by continuously monitoring the electrical current flowing through a circuit.
In a properly functioning circuit, the current flowing out on the live wire should be equal to
When the jordfejlstrømsafbryder detects a residual current above a certain threshold, typically 30 milliamperes (mA) for
Jordfejlstrømsafbrydere are essential safety components in modern electrical systems, particularly in areas where the risk of
