SOA category OS30
Internal electrical, telephone, radiotelephone and television systems
OS30 covers internal electrical and telecommunication systems in buildings and infrastructure: supply, installation and maintenance of electrical, telephone, data and television systems. Together with OS3 and OS28, it makes up the general category OG11 Technological systems. It is essential in every new build and renovation.
SOA certification OS30: areas of application
OS30 is needed wherever there are electrical and data systems inside a building. The main sectors:
- Residential buildings: power distribution, switchboards, residual current devices, earthing, lighting and provisions for electric vehicle charging.
- Public buildings and offices: schools, hospitals and institutional buildings, with LED lighting, emergency systems, cabling and Wi-Fi.
- Data networks: copper and fibre cabling inside buildings, server rooms and rack cabinets.
- Special systems: video surveillance, intruder alarms, access control, smoke detection, door entry systems and home automation.
- Industry and hospitals: ward switchboards, uninterruptible power supplies, emergency generators and medical rooms compliant with CEI 64-8.
In short: OS30 is the technological backbone of buildings, present in every modern project.

groups together OS3, OS28 and OS30. Companies holding OG11 can carry out OS30 works in the same classification.
OS30 is the most frequent separable category in OG1 and OG2 contracts; above 10% of the amount it must be stated in the call for tenders.
is the external twin of OS30: substations, power lines and public lighting. OS30 stops inside the building.
brings the operator’s fibre up to the technical room; from there to the sockets it is OS30.
OS30 powers and controls water and heating systems, from heat pumps to building management systems.
Why it pays to qualify in OS30
OS30 is the heart of Italian building services: no modern building works without it. Demand is growing due to:
· the energy transition, with photovoltaics and charging points;
· the digital transformation of offices, data centres and smart buildings.
If you work with electrical, telephone or data systems, obtain OS30 in the right classification in good time: it is the passport to a growing market and protects you from SIOS constraints.
