Here’s a simplified explanation of the difference between earthing and grounding 1. Earthing: Purpose: To protect people from electric shocks. Connected to: Non-current carrying metal parts of electrical equipment. When it works: During a fault (like insulation failure), it provides a path for fault current to the ground. Example: Metal body of a washing machine […]
Why do we need Ground, Earth, and Neutral-aren’t they all the same? 1. Ground (GND) Purpose: A reference point for voltages in a circuit. Carries Current? ldeally, no. Usage: Common in PCBS, signal integrity, and power return paths. 2. Earth (PE- Protective Earth) Purpose: Provides a safety path for fault currents. Carries Current? Only during […]
How to Read an MCB Nameplate? Understanding Miniature Circuit Breaker (MCB) nameplate data is crucial for selecting the right breaker and ensuring electrical safety. Here’s a breakdown of the key information printed on it: ✅ Model Number (e.g., C60N): Identifies the product series. ✅ Class & Current Rating (e.g., C20): ‘C’ represents the tripping curve, […]
RCCB vs ELCB vs RCBO: Know the Difference When it comes to electrical safety, it’s crucial to understand the distinct roles of RCCB, ELCB, and RCBO. Let’s break them down: 1️⃣ RCCB (Residual Current Circuit Breaker) Function: Detects leakage currents and trips to prevent electric shocks. Use: Protects humans from electrical faults (e.g., leakage to […]
