1. E lectric Shock & RCCB P resented by: Tanishq , Harsh, Adamya & Harman

2. I ntroduction Electricity is essential but can be dangerous. Electric shock can cause serious injuries or death.

3. RCCBs play a vital role in preventing electrocution. Understanding electric shock and RCCBs enhances workplace and home safety.

4. W hat is Electric Shock? Electric shock occurs when the human body becomes a part of an electric circuit, allowing current to flow through it.

5. Dangers of direct contact with live wires and its effects. 01 C auses: Hazards of faulty or damaged electrical appliances. Wet conditions increasing conductivity and electrical hazards. 02 03

6. E ffects: • Minor tingling sensations. • Severe burns and tissue damage. • Muscle contractions preventing self-release. • Heart disturbances and fatal cardiac arrest.

7. F actors Affecting Severity of Electric Shock : - Current Magnitude: Higher current = Higher risk. - Duration of Contact: Longer contact increases danger. - Path of Current: Through vital organs like the heart is more fatal. - Body Resistance: Wet skin reduces resistance and increases current flow .

8. F irst Aid for Electric Shock 1. Do NOT touch the victim directly if they are still in contact with electricity. 2. Turn off the power supply. immediately if possible. 3. Use a non-conductive object (wood, rubber) to separate the person. from the source. 4. Call emergency services. immediately. 5. Check for breathing and pulse:. Perform CPR if needed until medical help arrives.

9. P reventative Measures: - Always use insulated tools. - Wear rubber gloves when working with electricity. - Install safety devices like RCCBs.

10. RCCB (Residual Current Circuit Breaker) is a device designed to protect people from electric shocks caused by leakage current . I ntroduction to RCCB

11. H ow It Works: Constantly monitors current flow in live and neutral wires. -If any difference (leakage) is detected, it trips and disconnects the circuit. - Designed to react quickly to prevent electrocution and fires. W hy It’s Important: - Reduces risk of severe electric shocks. - Prevents electrical fires caused by leakage currents.

12. W orking Principle of RCCB Operation of RCCB: RCCB detects the imbalance in live and neutral currents. The imbalance (leakage current) could be due to a person accidentally touching a live wire. When the difference exceeds the set limit (typically 30mA for human safety), RCCB disconnects the power supply immediately.

13. Sensitivity ratings: 30mA (for human protection), 100mA+ (for fire prevention). - Response time: Typically, within 30 milliseconds. Technical Aspects:

14. A pplications of RCCB • Residential Buildings: Prevents household electrocutions. • Industrial Workspaces: Protects machinery and workers from accidental leaks. • Medical Facilities: Ensures safety of patients and sensitive medical equipment • Outdoor Installations: Ideal for gardens, swimming pools, and wet environments.

15. Conclusion - Electric shock is dangerous and can be fatal. - Proper safety measures must be taken. - RCCBs are essential for preventing electrocution and fire hazards. - Always ensure RCCBs are installed and regularly tested. Stay safe and prioritize electrical safety!
