⚡ 🔌 Simple Technical Explanation
✔️ MCB Breaker Terminals:
A typical MCB (Miniature Circuit Breaker) has two sides:
🔺 Upper Side = Input (Supply)
Main power comes in here
Phase and neutral are connected from source
🔻 Lower Side = Output (Load)
Power goes out from here
Connected to home wiring or appliances
⚠️ Correct Wiring Practice:
🔥 Upper terminals → Incoming supply (main line)
🔥 Lower terminals → Outgoing load (house wiring)
❗ Important Note:
Some breakers are non-polarized, but standard wiring practice is always: Top = Supply | Bottom = Load
Wrong connection may cause safety risks or heating issues.
⚡ Common Mistake:
Reversing input/output wires
Loose connections causing tripping or heating
