an voltage stabilizers protect against electrical shocks?

No, voltage stabilizers do not protect against electrical shocks.

Here’s why:

Voltage stabilizers are designed to:

• Regulate voltage (e.g., keep it within a safe range like 200–240V).
• Protect appliances from voltage fluctuations, surges, or under-voltage.
• Sometimes offer overload or short circuit protection for devices.

But they do not:

• Detect or prevent electric shocks to humans.
• Interrupt current flow in the event of accidental contact with live wires.
• Act like residual current devices (RCDs) or earth leakage circuit breakers (ELCBs)—which are designed specifically to detect leakage current and prevent electrocution.

For protection against electric shocks, you need:

• RCDs / RCCBs (Residual Current Devices / Circuit Breakers): These cut off power if they detect leakage current (e.g., someone touching a live wire).
• Proper grounding/earthing of appliances and wiring.
• Double insulation in appliances.
• Circuit integrity checks during installation and maintenance.
