The business of electric installations is not without its risk in an environment with heavy rain-falls and floods. Secure installations are relatively expensive and are therefore often neglected or omitted. The training is based on passing on knowledge within the “company”. As em-ployment is often short-term, a lot of knowledge and skills are lost. Consequently new tech-nologies are not promoted enough. Only what is known will be passed on. CVT offers a new, dual educational approach to fill this gap of professional education the electrician sector.
