Electrical Installation Manual

We prepare complete and customized manuals for each type of electrical installation, from residential systems to highly complex industrial systems. These technical documents describe, step by step, all recommended procedures for execution, operation, and maintenance of installations, always in compliance with current standards (such as NBR 5410, NBR 14039, and NR-10). Our manuals provide clear guidelines on safety, use of materials, electrical diagrams, symbols, and necessary precautions, ensuring that all project stages are carried out with excellence and standardization.

Technical Instructions and Procedures

We develop thoroughly documented technical instructions and procedures that guide teams in the safe and effective execution of all electrical activities. Each procedure is created based on technical standards, risk analysis, and industry best practices. We cover everything from preparing work areas to final commissioning tests, ensuring traceability and execution quality. This way, our clients benefit from a high technical standard and a solid foundation for training, audits, and certifications.

Lightning Protection System (LPS) and Grounding Reports

We carry out technical inspections and prepare detailed reports on the compliance of Lightning Protection Systems (LPS) and electrical grounding. Our reports contain measurements, diagrams, technical photographs, corrective recommendations, and conclusions based on ABNT NBR 5419 and NBR 5410 standards. We use certified equipment and experienced professionals to ensure reliable results, helping our clients meet legal and insurance requirements while reducing the risk of accidents and material damage.

Specification of PPE, Protective Conductors, and Tools

We assist our clients in selecting the most suitable Personal Protective Equipment (PPE), Protective Conductors (CPE), and tools for their operations. We consider voltage levels, associated risks, and regulatory requirements such as NR-10 guidelines and IEC 60900. Our specialists assess material quality, service compatibility, and compliance certificates, promoting a safer and more efficient work environment in full legal compliance.

Incident Energy Calculation – ATPV

We perform accurate incident energy (ATPV) calculations according to IEEE 1584 and NFPA 70E methodologies, essential for defining the correct PPE against arc flash. The study considers factors such as short-circuit current, protection opening time, and working distance. We provide a technical report with mapped risk zones, clothing and equipment recommendations, contributing to the prevention of serious accidents and strict compliance with safety standards.

Hazardous Area Classification Study (Ex)

We carry out surveys and classification of areas with explosive atmospheres risk, based on IEC 60079 and NR-20 standards. We assess flammable substances, ventilation systems, frequency, and duration of emissions to properly classify zones (0, 1, 2 or 20, 21, 22). This study allows for the correct selection of Ex equipment and defines operational safety criteria, being essential for preventing explosions in industrial facilities.

Ex Inspection – Visual / Close / Detailed

We conduct technical inspections in hazardous areas according to the three levels defined by ABNT NBR IEC 60079-17: visual, close, and detailed. Our team assesses the integrity of Ex equipment, connections, certifications, grounding, and signs of deterioration. We apply non-destructive methods and, when necessary, partial disassembly to ensure continuous system safety. Finally, we provide complete technical reports with photographic evidence and corrective action plans, ensuring compliance with international standards.

Technical Inspection Report

Our technical inspection reports document, with a high level of accuracy, the condition of electrical installations, equipment, and auxiliary systems. We include descriptions of non-conformities, photographic evidence, performed measurements, risk analyses, and technical recommendations. These documents are essential for audits, certifications, and strategic decision-making regarding corrective and preventive maintenance. All content follows technical standards and language consistent with regulatory and insurance requirements.

Electrical Installation Project Datasheet

We create complete datasheets for each electrical installation project, containing essential information such as installed power, cable sizing, electrical diagrams, single-line diagrams, protective device characteristics, selectivity curves, and construction methods used. This document is a technical guide that accompanies the project during its execution and also serves as a reference for future maintenance and expansions, ensuring transparency and traceability.

Single-Line Diagrams

We develop clear, accurate, and updated single-line diagrams, essential for understanding and maintaining electrical installations. These diagrams graphically represent circuits, breakers, busbars, panels, transformers, and other components. We follow NBR 8196 and NBR 5444 technical standards with standardized symbols, facilitating the work of engineers, electricians, and inspectors. We also review and update old diagrams to adapt them to the current installation reality.

Lighting Inspection

We evaluate lighting systems regarding illuminance level, uniformity, energy efficiency, luminaire positioning, compliance with NBR ISO/CIE 8995 and NR-17. This service is essential for corporate, industrial, and logistics environments that require proper visual conditions for productivity and worker safety. After inspection, we provide a report with lux measurements, improvement points, and recommendations for replacement or adjustments.

Outsourced Technical Responsibility

We offer the Technical Responsible (RT) service for companies that need to meet legal requirements with agencies such as CREA, municipalities, or insurers. We act with ethical and technical responsibility, assuming supervision of projects, execution, and maintenance of electrical installations. This solution is ideal for companies without an internal technical team or that wish to delegate responsibility to highly qualified and experienced professionals, with continuous support and issuance of official documents.

PPE, Protective Conductors, and Electrical Tool Testing

We ensure compliance and safety in the use of electrical protection tools and equipment through periodic tests such as dielectric testing, insulation resistance, and continuity verification. We check the integrity of PPE, grounding cables, switch sticks, gloves, insulated tools, and more. We also guide our clients on validity, storage, and replacement, promoting worker safety and operational efficiency.

Calibration of Fixed and Portable Electrical Instruments

We provide traceable calibration services for multimeters, megohmmeters, clamp meters, voltage detectors, power analyzers, and more. We work with certified metrological standards and provide calibration certificates valid for ISO audits, NR-10, and quality programs. This service is essential to ensure accurate measurements, safe operations, and technical compliance in regulated environments.

Audit Consulting

We provide technical consulting for companies that need to prepare for internal or external audits related to electrical installations, safety, energy efficiency, or regulatory compliance. We analyze documentation, physical installation conditions, team readiness, records, and maintenance history. Based on this, we suggest corrective and preventive actions so that the company is fully able to meet the legal and regulatory requirements demanded by certification bodies, insurers, or public agencies.
