Registration, safety training and ART: what makes the document valid
Before you sign anything, it is worth checking who signs. This page gathers the professional registration with the engineering council, the safety training required for electrical work and work at height, and the courses behind the testing methodology — with the hours and the year of the latest refresher for each.

Nothing is signed without authorisation. The professional registration is what turns a design or a report into a document the utility, the fire brigade and the insurer accept — and it is the origin of the ART record for each delivery.
Professional registration as electrical technician
CREA-SP · Brazilian engineering council (Confea/Crea)
Standing authorisation to practise electrical technology, registered with the professional council and kept active since 2013. It is this registration that gives legal force to low and medium voltage installation designs and enables the electronic ART record for each signed job. The registration number and its status are printed on the proposal and can be verified in the council's public registry.

Mandatory safety training
Electrical inspection is life-risk work, so training comes before the instrument. The year shown on each card is the latest issue or refresher, not the first attendance.
NR-10 — basic safety training for electrical installations and services
Regulatory standard NR-10 · Brazilian Ministry of Labour
Initial 40-hour training on electrical risks, control measures, de-energisation with lock-out, controlled zones and the minimum documentation an installation must hold. The procedure taught there governs every surveyed test: dead, signed and blocked, with an RCD check before any board is opened.

NR-10 — supplementary course for high and extra-high voltage work
NR-10 supplementary module · HV and EHV installations
Further training required for work on high and extra-high voltage installations: switching operations, clearances, protective equipment, safety roles and coordination with the utility delivery point. It underpins inspections of service entrances, switchgear cubicles and private substations.

NR-35 — work at height
Regulatory standard NR-35 · Brazilian Ministry of Labour
Training for work on roofs, towers and elevated structures, covering risk analysis, anchor points, positioning belts and emergency routine. It is what makes roof-level lightning protection inspection and photovoltaic module mounting possible without subcontracting.

Technical training
The courses behind the method
Solar, thermography, lighting design and energy management are not shelf services: each one joined the portfolio because a real job asked for it. These are trainings used daily, not certificates kept in a drawer.
Photovoltaic installation and inverter configuration
Technical course · distributed solar generation
Hands-on training in module layout, string design, DC and AC protection, isolation, structure earthing and generation monitoring. Includes inverter configuration to the technical connection rules, with the frequency response and ramp settings the distributor requires.

Thermography applied to electrical installations
Infrared inspection course
Testing technique with an infrared camera: emissivity setting, span and level adjustment, phase-to-phase comparison and recording of the load condition at the moment of capture. It is the method used to grade hot spots by criticality in thermography reports, with real temperatures and a reference in the document.

A standard is not memorised, it is consulted with judgement. The update courses exist to follow ABNT revisions and keep the calculation note and the test schedule coherent with the edition in force.
ABNT NBR 5410 update — low voltage electrical installations
ABNT · low voltage standard
Focused revision of the clauses that generate most non-conformities: selectivity and overload/short-circuit protection, 30 mA RCDs on the required circuits, minimum socket outlet count, spare circuits, minimum cross-section and voltage drop. The design calculation note is built from this check.

ABNT NBR 5419 update — protection against lightning
ABNT · lightning protection
Study of the standard parts that make up the system: risk assessment and protection level, air terminal and down-conductor layout, earth electrode grid, bonding and safe separation, plus SPDs for internal circuits. It is the basis of the lightning protection report and design.

How to verify the ART of a design or report
An ART is not decorative paperwork: it is the record linking a technical object to a qualified professional. Anyone can check it, and the check takes less than a minute.
Verification routine
Ask for the ART sheet or the document number — issued at delivery, together with the report
Confirm that the object described in the ART matches the contracted service (design, installation report, lightning protection report, thermography)
Check the technical lead's name and the standing of the registration in the council's public registry
Cross-check the installation address against the address declared in the document
Keep the signed PDF with the ART number: that is what the insurer and the inspecting body ask for later
If anything is unclear, ask the technical lead for clarification before filing
What an ART does not do
It does not replace the report and does not certify an installation indefinitely: it records technical responsibility for that object, on that date. A document without an ART, or with an ART whose object differs from what the authority requires, is usually returned during review.
Straight to the point: who signs, what it covers and how to verify.
Can an electrical technician sign an electrical design?
Yes, within the scope defined by the qualification and the professional registration: low voltage installations, service entrance designs, boards, lightning protection and condition reports. Broader electrical engineering work, such as power systems and substation protection, belongs to an engineer — and then the answer is a multidisciplinary team, with a qualified professional for each part.
Is the ART issued with the report or must I request it?
It is part of the delivery, no separate request needed. The filing is made with the technical object described — installation report, lightning protection report, design, thermography — and the number is printed in the document so the recipient can verify it.
Are the courses and certificates renewed?
The regulatory courses have a refresher interval defined in the standards themselves, and the cards on this page show the year of the latest issue or update. Training in design, solar and energy efficiency is reviewed whenever the reference standard changes edition.
