Loads, circuits, protections, switchboards and selectivity are assessed against long-term plant operation.
Electrical systems
Electrical systems engineered to distribute power safely, continuously and with full operational control.
From substations to technical loads, we engineer and install distribution, protection and connections under in-house technical responsibility.
Technical approach
Reliable electrical infrastructure depends on coordinated loads, protection, selectivity and documentation, not installation alone.
An electrical system must support real loads, changing requirements, safety, maintenance and continuity of service. We therefore treat it as a distribution infrastructure: every circuit, protection and connection must be correctly sized, identifiable and verifiable.
The internal design office develops diagrams, routes, sections, protections, switchboards and verification criteria. Elettrica System teams then build the systems with in-house personnel and company-owned equipment, ensuring consistency between drawings, site work, tests and final commissioning.
Elettrica System capabilities
Reliable distribution starts with clear decisions before installation begins.
In-house personnel and equipment manage containment, cabling, connections and associated work.
Testing, updated diagrams, labelling and as-built documentation support safety and future maintenance.
What we do
From primary distribution to end loads: an electrical system built to operate and to be managed.
Distribution and power systems
Backbones, lines, cableways, power supplies, protections and connections for technical, production and service users.
Switchboards, protections and coordination
Integration with MV/LV switchboards, selectivity, protections, isolations, power continuity and future expansion requirements.
Lighting, emergency and services
General lighting, emergency lighting, service power supplies and connections to special systems.
Checks, commissioning and documentation
Instrumental tests, functional checks, labelling, updated diagrams, as-built documents and maintenance support.
Operating phases
A complete technical process, from initial requirement to handover.
Requirements
Loads, users, constraints, safety, continuity, required performance and maintenance criteria.
Sizing
Lines, switchboards, protections, routes, materials, selectivity and coordination with other systems.
Construction
Installation, wiring, connections, intermediate tests and field installation control.
Testing and commissioning
Final checks, documentation, technical handover and guidance for future system management.
Applications
For buildings and infrastructure where power cannot become an operational uncertainty.
Industry
Commercial buildings
Public buildings
Logistics
Infrastrutture tecniche
The value is not simply available power. It is the ability to isolate, verify, extend and maintain the system without turning every intervention into an operational risk.

The most common questions about electrical systems.
How are electrical systems sized?
Electrical systems are sized taking into account loads, usage profiles, service continuity, discrimination, short-circuit conditions, voltage drops and any future expansion. The design complies with technical standards and the client's requirements.
Who physically builds the system?
The system is built by qualified technicians, coordinated by the project manager and the technical management. Any specialist companies work under Elettrica System's control for quality, safety and scheduling.
What is delivered once the work is complete?
On completion, the client receives the tested system, as-built documents, inspection reports, manuals and the declarations required by regulations. This documentation makes operation, maintenance and future expansion easier.
What settings are these systems designed for?
Elettrica System designs and builds electrical systems for residential, commercial and industrial use, as well as for hospitals, infrastructure and public buildings. Each solution is calibrated for safety, reliability and energy efficiency.
