What is an electrical panel?

The electrical panel is the point where the distribution and protection of an installation's electrical circuits are centralized.

Key components

  • Main switch.
  • Miniature circuit breakers (MCBs).
  • Residual current device (RCD).
  • Neutral bar.
  • Grounding bar.
  • Contactors and auxiliary relays where needed.

Why proper layout matters

A well-organized panel is safer, easier to maintain, and helps in quickly identifying a fault.
