Electrical installations dossier (PIE)
The documentation NR-10 requires to be kept organised, up to date and available to labour inspectors.
Who needs it
Under the new NR-10 (item 10.15.6), organisations that are part of the electrical power system (SEP) or that carry out work on medium or high voltage installations must organise their documentation as an Electrical Installations Dossier. Until 31 May 2027 the previous rule applies: the dossier is mandatory for sites with installed load above 75 kW.
Companies not required to keep the dossier must still keep documentation: the electrical design and records of earthing inspection and measurement (item 10.15.3) and, if they have authorised workers, procedures, risk analyses, work permits and training records (item 10.15.4).
NR-10 (Safety in electrical installations and services) is backed by arts. 179–181 of the CLT. It was rewritten by MTE Ordinance No. 737/2026, published on 1 June 2026, which takes effect on 1 June 2027. Until then, the previous text applies.
What you receive
- preparation of all technical documents in the dossier;
- review of the documentation the company already has;
- organisation of the complete dossier, digital or printed, in Portuguese (item 10.15.1);
- ART registered with CREA.
Remote delivery
The dossier is a set of documents: for plants that already have an up-to-date design or single-line diagram and earthing measurements, it can be prepared remotely, based on the documents and data sent by the company. The inspection of the installations is a separate, on-site service: the NR-10 inspection.
