Download Proposition
Section titled “Download Proposition”This is a proposed approach for the kitchen electrical work. Please review and feel free to adapt based on your professional experience and what works best for the installation.
The spreadsheet includes the proposed circuit layout, component list, and wiring approach. You can print it, add your notes, or adjust the plan as needed.
Overview
Section titled “Overview”Objective: Complete electrical installation for new kitchen.
Location: Ground floor, new kitchen area Electrical Panel: Ground Central 2 (G2)
Electrical Panel Information
Section titled “Electrical Panel Information”Ground Central 2 (G2) is an old-style electrical panel with porcelain fuses and 3 small DIN rails that would be the preferred spots for the new kitchen.
DIN Rail Layout Plan
Section titled “DIN Rail Layout Plan”Each DIN rail is 20cm long (9-10 module positions). Kitchen circuits would ideally be consolidated onto DIN rails using rail-based numbering:
- Rail 1 (Phase 1): G2-11 to G2-19 (continues with G2-1A, G2-1B etc)
- Rail 2 (Phase 2): G2-21 to G2-29
- Rail 3 (Phase 3): G2-31 to G2-39
A 4th rail could be considered for future consolidation of 3 phase circuits (oven and sauna).
RCCB Wiring Approach: One RCCB per phase. Circuits requiring RCCB protection are wired through the RCCB; circuits not requiring protection are wired directly from RCCB input (bypass). This provides flexibility without vendor lock-in (no busbar desired here).

Rail 3 - Phase 3 (5 modules used, 4-5 free)
Section titled “Rail 3 - Phase 3 (5 modules used, 4-5 free)”Components:
- 1x RCCB (2 modules)
- 3x Circuit breakers (3 modules total)
Circuits: 8. G2-31 (16A breaker) - Washing machine

Reference Documentation
Section titled “Reference Documentation”Scope of Work
Section titled “Scope of Work”1. DIN Rail Installation & Wiring
Section titled “1. DIN Rail Installation & Wiring”Most kitchen circuits are consolidated onto DIN rails using rail-based numbering (G2-11 to G2-33). See DIN Rail Layout Plan above for complete component list and wiring approach.
Key wiring requirements:
- Install 3x RCCB (one per phase)
- Wire socket circuits through their phase’s RCCB
- Wire lights, fridge, and heaters bypassing RCCB (direct from RCCB input)
- Move some wires from old porcelain fuses to new DIN rail breakers
Circuits with RCCB protection (wired through RCCB):
- G2-11: Kitchen wall sockets (Walls 1 & 2)
- G2-21: Dishwasher
- G2-22: Hood fan + island socket
- G2-31: Washing machine
- G2-32: Kitchen wall sockets (Wall 3, windows)
Circuits without RCCB (bypass wiring):
- G2-12: Wall heater (domino)
- G2-13: Fridge (isolated, avoid nuisance tripping)
- G2-23: Wall heater (stock)
- G2-24: Kitchen lights
- G2-33: Wall heater (chimney room)
