What is a RCD/GFCI?

A GFCI (Ground Fault Circuit Interrupter) /RCD(Residual Current Device) is a critical safety device built into this extension cord.

It continuously monitors the electrical current flowing through the connected devices. If a fault is

detected (e.g., you accidentally touch a live wire), the RCD/GFCI will automatically cut off the power,

greatly reducing the risk of electric shock, fire, or serious injury.
