Compliance with electrical standards

Electrical Standards 

The calculation methods used in elec calc are based on the standards, guides and best practices as well as the personal safety regulations in force in different countries. 

Natively, elec calc complies with IEC standards. 

Other standards are implemented to meet the country’s specific requirements: 

  • NF for France 
  • RGIE/AREI Regulation for Belgium 
  • NIBT Standard for Switzerland 
  • REBT Standard for Spain 
  • VDE Standard for Germany 
  • NEN Standard for the Netherlands 

The main reference documents used in elec calc are:
