GREI Masterclass Fully up to date with the GREI

With this GREI masterclass, you will be up to date with the very latest regulations in the field of electricity.

The GREI, or General Regulations on Electrical Installations, was thoroughly updated on June 1, 2020. Every few months, many new elements are added, such as regulations regarding EV charging stations, home batteries, and solar panels. We follow these developments closely and ensure that the GREI masterclass always includes the very latest updates.

It is essential for technical professionals to stay informed about the GREI to ensure that company installations remain compliant.
