Review of Electrical Equipment in Explosive Atmospheres Qualification and Unit Standards

Qualification Review 

A group of industry representatives, facilitated by Waihanga Ara Rau, has completed the review of the following qualification:

NZC in Electrical Equipment in Explosive Atmospheres (Level 4) [Ref: 3614] with optional strands in

  • Explosion-Protected Electrical Equipment Installation
  • Explosion-Protected Electrical Equipment Inspection, and
  • Explosion-Protected Electrical Equipment in Underground Mines


  • Include outcome for the installation strand in the core qualification and reduce the overall credit to 40 credits
  • Remove the inspection strand as this is higher than Level 4
  • Remove the underground mines strand as this is no longer useful in New Zealand
  • Develop micro-credentials where needed, for example, inspection and gas detection.

The reviewed qualification can be viewed here.
