Power Cable Selection for PV Systems


Online Short Course

Power Cable Selection for PV Systems is an online technical course that explores selecting power cables based on the Australian Standard, AS/NZS 3008.

 In this course, learners will be taken though each step of the cable selection process as outlined in AS/NZS 3008, with a strong focus on compliance, performance and design best practices to ensure a smooth transition from the design to installation phase of a project. Different sizing and selection methods for DC, single phase AC and three phase AC cables are included. The course content includes:

  • Basic principles of cable selection
  • Sizing based on current carrying capacity
  • Sizing based on voltage rise and drop
  • Sizing based on short circuit temperature limit
  • Economic considerations
  • Using software

Is this course for you?

This course was designed primarily with commercial and industrial (C&I) systems in mind. If you are looking to enter the solar C&I industry, this will be the perfect course for you to perfect your cable selection skills. The same fundamental skills can be applied to all levels and sizes of PV systems so consider enrolling in this course if you want to gain a more in-depth understanding of the cable selection process.

This course is eligible for 5 hours professional development with Engineers Australia
