All content will be based on legislation currently applicable, mainly in the RTIEBT. DEMONSTRATION OF THE CONSISTENCY LEARNING METHODOLOGIES WITH THE TEACHING/ LEARNING OBJECTIVES The area of project, execution and operation of electrical installations has a strong component at the level of legislation, regulations and best practice work. As such, students are encouraged to consult and handle all regulatory documentation applicable to this matter, based on the RTIEBT as well as other applicable legislation. The body of work that students will develop will aim to consolidate their respective expertise and practical applicability.
