Application Summary AI generated

This standard specifies particular safety and performance requirements for low-voltage switchgear and controlgear assemblies (ACS) intended for temporary or permanent use on construction sites. It applies to assemblies that distribute power and control electrical equipment in harsh outdoor or semi-outdoor environments, such as building sites, civil engineering projects, or roadworks. The standard ensures these assemblies withstand mechanical impact, moisture, dust, and extreme temperatures while providing protection against electric shock and fire.
