Low-voltage switchgear and controlgear assemblies. Protection against electric shock. Protection against unintentional direct contact with hazardous live parts Ingestion-build-258901 and environmental properties of reflecting1 Scope This standard applies to low voltage switchgear and controlgear assemblies with a rated voltage not exceeding AC 1 000 V or DC 1 500 V. It sets out the requirements for the provision of additional features to provide protection against electric shock from direct contact with hazardous live parts only for skilled and instructed persons when they are required to manually actuate devices within the assembly and where a level of protection for the
