List two safety devices that are used in domestic electric circuits. - Leaving Cert Physics - Question b - 2005

Two common safety devices used in domestic electric circuits are:

1. Fuse: A fuse is designed to protect electrical circuits from overloads and short circuits by melting and breaking the circuit when the current exceeds a safe level.

2. Residual Current Device (RCD): An RCD continuously monitors the current flowing through the circuit and disconnects the power when it detects an imbalance, which can indicate a leakage current, thereby preventing electric shocks.
