NEN 3840

Certification Matters. In high voltage, the stakes are high. Every decision, every action, can have far-reaching consequences for the success of a project and for the safety of those involved.

Stay sharp as a fox

NEN 3840 is the Dutch standard for the safe execution of work near, on or with electrical objects in the high-voltage area. Upon certification, you join a community of professionals committed to excellence, ensuring personal safety, protecting teammates and driving project success by mastering electrical basic principles, strict safety protocols and applicable safety and quality standards. In a world where the stakes are this high, certification isn’t just necessary – it’s essential.
