NEN 3140 training

*NEN 3140, based on NEN-EN 50110, is a standard that contains all relevant requirements for low voltage installations for the Netherlands. NEN 3140 applies to the operation of electrical installations and equipment up to a nominal voltage of 1000 V AC and 1500 V DC.

Employers are obliged to ensure that employees who work on or near electrical low-voltage installations are competent enough and that it is also clear who can do what and who is responsible for what (Working Conditions Act article 3.2). Employees of companies that work with or on electrical installations must be aware of the dangers and risks that the work entails.

The IP NEN 3140 training is intended for anyone who performs simple work on electrical installations or who wants to be appointed by his or her employer as a instructed person (IP) (=VOP in Dutch) in the context of NEN 3140. As a follow-up to the NEN 3140 IP basic training, it is also possible to follow the refresher training.

Course Contents

During this 1-day (8-hour) training day, our certified instructors will teach you all the hazards and risks you need to know to safely perform simple work on electrical installations. You will also learn to limit the dangers and risks as much as possible. With a IP certificate, the employee proves that he or she knows, recognizes and can prevent electrical risks with specific measures and knows where his or her responsibility begins and ends.

NEN 3140+A3:2019 (Operation of electrical installations – Low voltage) states how companies comply with this working conditions obligation and how they can prevent electrical risks. Topics covered include:

  • Electrical Hazards and Accidents
  • Electrical engineering management and legislation

The NEN 3140 IP basic training takes one day. When you successfully complete the basic training, you will receive a NEN 3140 certificate and Doornbos pass. These are valid for three years.
