Industrial Electrical Maintenance

Aims & Objectives

The aim of the industrial electrical maintenance course is to provide solid foundations upon which the participant will be able to build and develop. Emphasis is given to providing the necessary skills, which will allow the participant to carry out routine electrical tasks. It is also made clear that a participant needs to identify and know their own limitations, allowing tasks to be carried out in a safe manner, not giving rise to danger.
