Learning outcome

The course will give the students good skills in planning and dimensioning of low voltage installations for industry, residential and non-residential buildings.

Learning methods and activities

Lectures, compulsory exercises and laboratory work. Compulsory project work. The final evaluation will be based on a written examination (counting 70%) and the project work (counting 30%) based on % fulfillment. Final grading will be from A to F. If there is a re-sit examination, the examination form may change from written to oral.
