The ECA will present an online SANS 10142-1 course for all electrical contractors and Chris Koen, Regional Director of the Highveld region, says this all-new course is a ‘journey’ through the whole of SANS 10142-1 (Ed 3) from one cover to cover and will be held over 20 sessions of at about two hours each, twice a month. Anthony Schewitz will co-present the course, which is targeted at both the licensed electrician who wants a deeper understanding of the code of practice and at students who would like to go through the entire code before writing exams.

The cost of the course is only R350 per session for members and R600 per session for non-members.  Course material is included and will be emailed to all students.

Courses will all be recorded for review and made available to all students who have paid and booked for the course.

The classes will take place on Wednesdays, starting at 10 am and finishing at around 1 pm. It is envisaged that the course will take an average of two to four hours per session.
