Why choosing an ANRE-certified installer matters

Industrial electrical installations leave no room for compromise. A poorly designed or executed system can lead to serious consequences: costly equipment failures, fire hazards, or electrocution risks. In Romania, legislation requires that the design and execution of electrical installations be carried out exclusively by operators certified by the National Energy Regulatory Authority (ANRE).

ANRE certification is far more than a bureaucratic formality. It confirms that the company has qualified personnel, the necessary equipment, and work procedures that comply with current technical standards.

Types of relevant ANRE certifications

ANRE issues several types of certifications depending on the category of work:

  • Type A — electrical installation design
  • Type B — electrical installation execution
  • Type C — electrical installation verification

For a complete industrial project, it is essential that the contracting company holds at least Type A and Type B certifications, covering both the design and execution phases.

Applicable standards and regulations

The main regulations governing industrial electrical installations in Romania include:

  • Normative I7 — standard for the design, execution, and operation of building electrical installations
  • PE 116 — standard for testing and measurement of electrical equipment and installations
  • NTE 007 — standard for the design and execution of electrical cable networks
  • SR EN 60204 — safety of electrical equipment for industrial machines
  • SR EN 61439 — low-voltage switchgear and controlgear assemblies (electrical panels)

Compliance with these standards is not optional — it is a legal requirement that protects both the investor and the end users of the installation.

Stages of an industrial electrical project

1. Audit and requirements analysis

Every solid project begins with a detailed assessment of needs: required electrical capacity, types of equipment to be powered, environmental conditions (temperature, humidity, corrosive substances), and specific requirements of the industrial process.

2. Installation design

Based on the audit, technical documentation is developed: single-line diagrams, cable routing plans, cable and protection sizing, technical specifications for electrical panels and equipment. The project must be signed by an ANRE-certified designer.

3. Execution and installation

Execution work includes: mounting electrical panels, laying cables along routes (cable trays, conduits, cable ladders), making connections, installing lighting fixtures and outlets, and establishing earthing systems.

4. Testing and verification

After installation is complete, mandatory measurements and tests are performed: insulation resistance, continuity of protective conductors, earth resistance, and operation of residual current devices. All results are documented in verification reports.

5. Acceptance and commissioning

The final stage involves reviewing documentation, verifying that execution conforms to the design, and obtaining the necessary approvals from the electricity supplier.

Common mistakes to avoid

  • Under-sizing protections — selecting circuit breakers with insufficient amperage leads to frequent tripping or, worse, ineffective protection.
  • Non-compliant routing — cables laid without respecting minimum distances from other utilities or without adequate mechanical protection.
  • Missing documentation — a project without complete documentation becomes impossible to maintain and expand later.
  • Cutting costs on quality materials — cheap cables and equipment may seem cost-effective short-term but generate much higher costs through premature failures.

Why choose an experienced partner

An industrial electrical installation project is a long-term investment. Choosing a company with proven experience, full ANRE certification, and partnerships with renowned manufacturers (such as Reichle & De-Massari for network components) ensures:

  • 100% compliance with legislation and standards
  • Quality materials with extended warranties
  • Complete documentation for future interventions
  • Long-term technical support and maintenance
