4. Protect Your Equipment: Choosing the Right Incoming Protection – MCB, RCBO, ELCB or Main Switch?

Your board is only as safe as its incoming protection system. Let’s break down the options:

⚡ Incoming Protection Devices:

• MCB (Miniature Circuit Breaker)
  Protects against overloads and short circuits.
• RCBO (Residual Current Breaker with Overload)
  Combines MCB and ELCB features — best protection against earth leakage and overload.
• EL+MCB (Earth Leakage Circuit Breaker)
  Disconnects the supply if leakage current is detected with add on protection from overload.
• RCCB -A Residual Current Circuit Breaker (RCCB) is an electrical safety device that protects against earth leakage currents.
  

Ideal Combinations:

• MCB : Basic over current protection
• RCBO Only: Compact and efficient for mobile panels
• MCB + ELCB:
