The publication of a new edition of a technical standard always warrants careful attention: on one hand, because of the sensitivity and criticality of the matters it seeks to regulate; on the other, because of its role in providing uniformity and a reference framework for companies, consumers and all other stakeholders. When CEI, the Italian Electrotechnical Committee \u2014 the authoritative Italian standardisation body in this field \u2014 issues an update, it is important to understand the changes taking place, bearing in mind that companies will probably be required (or rather, recommended) to apply even greater organisational rigour in managing activities that carry potentially very significant risk, such as work on electrical installations \u2014 i.e. operations and work activities on or connected to electrical installations, now regulated by the new CEI Standard 11-27:2021. This consolidates its function as a single, codified tool designed to satisfy the mandatory requirements of national and European legislation. The new standard applies to installations (fixed, mobile, permanent and temporary) at any voltage level, for which updated safety requirements are provided, particularly in the form of work and operating procedures during works or maintenance. CEPER therefore considers it important to review these developments in a structured way, through a two-part analysis (in two successive articles), aimed at illustrating the changes from the perspective of the figures involved and their assigned duties, the scope of application (including any exclusions), and the practical organisational arrangements for carrying out works. This first part addresses:<\/p>\n

QUALIFICATIONS AND REQUIREMENTS OF PROFESSIONAL FIGURES: KEY DEVELOPMENTS<\/strong><\/p>\n

The standard on “Work on Electrical Installations”, 2021 edition, updates the 2014 version of the same name, with a number of significant amendments and additions. With particular reference to the designated professional figures, their responsibilities and the related professional and training requirements, the following noteworthy updates are identified.<\/p>\n

Regarding the Installation Manager (RI),<\/u> the definition in paragraph “3.2 Professional figures” clearly establishes that this figure’s role applies “during work activities”. <\/strong><\/p>\n

The RI is now defined as “the person designated to operate the electrical installation during work activities”; previously, the role was more generically linked to “operation of the installation”, without a clear reference to actual work execution. The standard further reaffirms, by means of a specific note, that the RI must be designated as a PES, i.e. a Skilled Person for carrying out electrical works. The PES qualification applies not only to operational figures, but extends also to additional technical personnel who, although not having an operational role in electrical works, are involved in the work execution process.<\/p>\n

The so-called URL, i.e. the Unit Responsible for Work Execution<\/u> \u2014 tasked with ensuring adequate organisational and technical conditions “upstream” \u2014 now explicitly bears responsibility for both “preparing” and “executing the work”<\/strong>.<\/p>\n

Here too, the standard emphasises the operational role assigned to this Unit (or rather, the person responsible for the Unit), indicating that it holds overall responsibility for work execution, not merely its preparation. This amendment may be understood as an intention to ensure greater involvement in maintaining adequate oversight of the actual activities of the figures (starting with the specifically delegated RI) who actively organise and execute works, and is therefore significant in terms of the operational oversight and supervision required in managing activities.<\/p>\n

Regarding requirements for personnel assigned to electrical works<\/u>, paragraph “4.2.2 Personnel assessment” now explicitly requires “basic knowledge of electrical engineering”, replacing the more generic “knowledge of electricity”<\/strong>.<\/p>\n

Basic knowledge of electrical engineering naturally presupposes an appropriate educational background (e.g. a professional course and\/or diploma, a university examination, etc.). It is more difficult \u2014 although it cannot be entirely excluded \u2014 to demonstrate that such knowledge derives solely from practical experience (which is in any case also required under the following point).<\/p>\n

The paragraph on training requirements (4.15.5) contains the most significant developments.<\/u><\/strong><\/p>\n

First, regarding “Level 1B \u2014 Knowledge and skills for operational activity”, the need for the training programme to include practical hands-on training, simulations, on-the-job mentoring<\/strong> (and\/or other useful but unspecified initiatives), in addition to classroom or distance-learning courses for theoretical components, is now explicitly stated.<\/p>\n

The following clarifications on training are also provided:<\/strong><\/p>\n
