Electrical installations
Residential and commercial electrical installations
Low-voltage and weak-current systems
Connection to the grid & metering
- Connection to the supplier’s grid and installation of panel/meter
- Power supply cables up to the main distribution board (correct sizing)
- Documentation and support for approvals and energizing
Indoor wiring & routing
- Wiring in protective conduits (concealed or surface-mounted), bends and secure fixings
- Junction boxes and outlet/switch boxes correctly positioned
- Separate circuits: lighting, general sockets, heavy consumers (oven, hob, heat pump, boiler)
Distribution board
- Main board and/or sub-panels; organized by circuits
- MCB and RCD/RCBO for short-circuit and electrocution protection
- Type 2/3 SPD for surge protection; labeling and board schematics
Indoor/outdoor lighting
- Ceiling/wall fixtures, spotlights and LED strips
- Outdoor lighting for yard, pathways and façade
- Motion sensors, dusk sensors or timers (optional)
Sockets and electrical devices
- Standard sockets and dedicated circuits for appliances
- Simple/Two-way/Cross switches, dimmers
- Data/TV/phone outlets, USB or smart sockets on request
Protections, grounding & lightning protection
