The technical regulation TR CU 004/2011 On safety of low-voltage equipment represents the minimum safety requirements for electrical equipment in order to protect life, health, property, and environmental as well as protecting consumers against misleading information.

According the Technical Regulation TR CU 004/2011, electrical devices shall be designed and manufactured in such a way that when used as intended they protect against the following:

  • electrocution
