Albanian electrical distribution box classification

In Albania, electrical distribution boxes are generally classified by voltage level, installation type, and intended use, following European standards and local regulations.Classification by Voltage LevelElectrical distribution boxes in Albania are typically categorized according to the voltage they handle, reflecting the structure of the national electricity system managed by OST sh.a.:Low Voltage (LV): Up to 1 kV, used in residential, commercial, and small industrial installations.Medium Voltage (MV): 1 kV to 35 kV, used in local distribution networks connecting substations to larger consumers.High Voltage (HV): Above 35 kV, primarily in substations and industrial facilities, though HV boxes are less common in standard distribution networks .Classification by Installation TypeDistribution boxes are also classified based on their physical installation:Indoor Boxes: Installed inside buildings, often wall-mounted or embedded, protecting circuits in residential or commercial settings.Outdoor Boxes: Weatherproof and often lockable, designed for street-level or substation use, resistant to environmental factors.Classification by Function and ComponentsDistribution boxes can be further classified by their function and internal components:Main Distribution Boards (MDBs): Centralized boxes distributing power to multiple circuits, often including circuit breakers, fuses, and metering devices.Sub-Distribution Boards (SDBs): Smaller boxes branching from the main board to serve specific areas or equipment.DIN Rail Boxes: Modular boxes using DIN rail-mounted components, common in Albania for residential and commercial installations, often supplied by distributors like Albaelettrica .Compliance and StandardsAlbanian electrical distribution boxes generally comply with European standards (IEC/EN) for safety, protection, and installation. This includes:IP Ratings: Indicating protection against dust and water ingress.Seismic Anchors: For areas requiring structural stability, as provided by local distributors.Circuit Protection: Integration of residual current devices (RCDs) and miniature circuit breakers (MCBs) for safety .SummaryIn practice, Albanian electrical distribution boxes are classified by:Voltage level (LV, MV, HV)Installation type (indoor, outdoor)Function (main, sub, modular/DIN rail)Compliance with European safety standards (IP rating, circuit protection, seismic anchoring) This classification ensures safe, reliable, and standardized electricity distribution across residential, commercial, and industrial sectors in Albania.
