DESIGN & INSTALLATION
An installation designed for its environment.
Our approach
Every electrical installation must suit its intended use.
A well-designed installation accounts for loads, circuits, environmental conditions, maintenance access and protective devices. Technical choices must suit the building or equipment application.
Work may cover commercial premises, technical buildings or selected industrial applications. Scope, equipment characteristics and required tests must be defined before execution.
- Assessment of electrical loads and requirements.
- Circuit organization and protection selection.
- Selection of suitable cables and routing methods.
- Verification and documentation according to the agreed scope.
Our service areas
The essential components of your installation.
Solutions are defined according to site characteristics, operating requirements and applicable electrical rules.

06
Industrial installations
Equipment wiring, machine power supply and integration of control circuits within the defined scope.

Electrical distribution
Organized circuits and suitable protection.
Distribution boards route power to designated circuits. Their design must consider loads, conductor characteristics, short-circuit conditions, protective-device coordination and operational access.
Breaker ratings, cable sizes and protective devices must be selected through technical assessment and applicable rules. Values should not be chosen solely from visual estimates.

Checks and testing
01 / VISUEL
02 / CONTINUITÉ
03 / ISOLATION
04 / FONCTIONNEMENT
Verify before commissioning.
Checks are determined by installation type, applicable requirements and work scope. They must be performed by competent personnel using suitable instruments.
Visual inspection
Condition of cables, fixings, enclosures, labels and access.
Electrical continuity
Required checks of protective conductors and relevant bonding.
Insulation resistance
Tests appropriate to circuits and equipment under applicable rules.
Functional testing
Verification of controls, protection and intended functions.
Our methodology
ÉTAPE 01
ÉTAPE 02
ÉTAPE 03
ÉTAPE 04
A structured process, from survey to verification.
Exact steps depend on the work scope, available documentation and customer requirements.
Site assessment
Identify applications, loads, constraints and existing installations.
Technical design
Define the required circuits, components, protection and cable routes.
Installation
Carry out the agreed work using the required precautions.
Verification and handover
Perform agreed tests and provide the specified documentation.
Electrical safety
Safety must be built in from the design stage.
Electrical work presents risks of electric shock, arc flash, burns and fire. It must be planned and carried out by competent personnel under applicable rules.
Before work
Energy sources, hazards and working conditions must be identified before work begins.
- Identify and isolate energy sources according to the applicable procedure.
- Verify absence of voltage using an appropriate method.
- Use protective equipment suited to the hazard.
Before commissioning
Energization takes place after necessary checks and resolution of conditions that could prevent safe commissioning.
- Check installation and identification labels.
- Perform tests appropriate to the circuit.
- Document defects and necessary corrective actions.
Frequently asked questions
Prepare your electrical project.
Every installation is different. A description of the site, intended use and expected work helps define the scope.
Request an assessment ↗What types of electrical installations are covered?
The page primarily covers wiring, distribution, lighting, outlets, earthing, protection and selected industrial applications. Scope must be confirmed for each project.
How is cable size determined?
Cable size depends on factors including design current, length, installation method, temperature, grouping, voltage drop and fault conditions. It must be determined through technical assessment.
Is earthing necessary?
Earthing and protective bonding arrangements depend on the electrical system, equipment and applicable rules. Their design and verification are essential safety considerations.
Do you perform electrical tests?
Checks and tests may be included in the agreed scope depending on installation type, available instruments, required competence and applicable rules.
Can you work on an existing installation?
Work on an existing installation requires assessment of its condition, documentation, protection and safety conditions before the work is defined.
