Electrical project for a workshop and garage
A 40-seat café with a professional kitchen, refrigeration equipment and emergency lighting requirements.
📊 Project specifications
| Type Workshop + garage | Area 120 m² |
| Phases Three-phase (380 V) | Calculated load 25 kW |
| Groups 16 | Welding 1 point |
| Design time 2 evenings |
🎯 Task
Power for a 3-phase lathe, milling machine, welding point, compressor, lighting 300 lx and sockets along the walls.
💡 Solution
Dedicated circuits for machines with motor protection, welding socket 3×6 mm² C32, compressor with soft start, lighting in 2 groups, socket grid on 4 circuits. RCD 30 mA on socket circuits.
- Kitchen split into dedicated groups with 30% power reserve.
- Emergency lighting on a separate line.
- Main breaker and RCD selected by calculated current.
- PDF set handed over for approval.
✅ Result
The project is ready for installation: SLD, plan, specification, cable schedule. The panel with motor breakers and thermal relays is fully assembled.
