A safe electrical system is built on correctly selected protection and a distribution board. Selection is based on load, line cross-section and standards (IEC).
| Component | Purpose / selection |
|---|---|
| Breaker (MCB) | Line protection against overload/short circuit. Rating (6–63A) to match cable size; B/C/D curve by load type |
| RCD | Earth-leakage protection (30mA — personal protection; 100–300mA — fire protection) |
| RCBO | MCB + RCD in one module — saves space |
| MCCB | High-current lines (63A+) with adjustable protection |
| Distribution board | With spare modules (expansion); IP20 indoor, IP65 outdoor/wet |
| SPD | Protection from voltage surges (lightning/switching) |
Selection principle: breaker rating ≤ cable's rated current. E.g. 2.5mm² copper ≈ 16–20A. Every wet/outdoor circuit requires a 30mA RCD. Leave 20–30% spare in the board.
Brands: Schneider Electric, ABB, Legrand, Hager — certified, IEC-standard, long-term reliable.
