A circuit breaker tripping repeatedly is a common sign of electrical faults at home. This usually happens when high-wattage appliances like microwaves, hairdryers, or irons draw more power than your electrical system can handle.

Common Causes of Circuit Breaker Tripping

• Overloaded circuits – Too many appliances running at once exceed the circuit’s limit.
• Short circuits – Faulty wiring or damaged insulation can cause sudden power surges.
• Ground faults – Electricity escaping to the ground due to damaged wires or moisture exposure.

Quick Fixes

Reduce appliance usage – Avoid running multiple high-watt devices on the same circuit.
Distribute power load – Use different outlets or circuits for high-energy appliances.
Check for faulty wiring – If tripping persists, have an electrician inspect for electrical faults at home.

If your circuit breaker keeps tripping, it could indicate a serious wiring issue. Contact a professional electrician to diagnose and fix the problem before it leads to bigger electrical hazards.

4. Electric Shocks: Dangers & Safety Measures

An electric shock can be painful and dangerous, and in severe cases, even fatal. These usually occur when a person comes into direct contact with live wires, faulty electrical appliances, or exposed outlets.

Common Causes of Electric Shocks

• Faulty wiring – Exposed or frayed wires increase the risk of accidental shocks.
• Damaged appliances – Broken insulation can leak electricity.
• Water exposure – Wet hands or damp environments amplify the danger.
• Overloaded circuits – Plugging too many appliances into a single outlet increases electrocution risks.

Safety Measures to Prevent Electric Shocks

Turn Off the Power – Switch off the circuit breaker if you suspect an electrical fault.
Avoid Handling Appliances with Wet Hands – Always dry your hands before touching electrical devices.
Inspect Cords and Outlets – Replace any damaged cables immediately.
Use Residual Current Devices (RCDs) – These cut off power in case of an imbalance, preventing severe shocks.
Hire a Professional Electrician – If electric shocks occur frequently, seek expert help.

What to Do If Someone Suffers an Electric Shock?

Turn off the power or push the person away using a non-conductive object.
