Testing that informs the next maintenance decision.

Our electrical maintenance case studies show the scope of work, recorded findings and follow-up needs behind each project. From fixed-RCD testing to asset-level reporting, the focus is on evidence that helps facilities teams manage their electrical infrastructure. Explore our commercial electrical maintenance programs to plan the next step.

What our reporting includes.

Clear records help facility teams understand the work completed and what happens next. Depending on the agreed scope, reporting includes:

  • Asset, circuit and location identification.
  • Inspection findings and recorded test results.
  • Failed items and action taken or required.
  • Repair and retest records where completed.
  • Requirements for the next maintenance visit.

Requirements shaped by the site.

Testing methods and intervals depend on the equipment, operating environment and applicable requirements. Our project pages explain how Australian Standards and NSW workplace requirements relate to each type of testing.

Project questions

Electrical maintenance and reporting.

What happens when equipment fails?
The result is recorded and the item assessed for appropriate action. The Sarah Redfern project records seven failed items removed from service; the Robert Townson RCD project records failures requiring follow-up. Each case study distinguishes testing findings from completed corrective work.
Can testing be scheduled around school operations?
Discuss access, school hours, examinations and shutdown requirements when planning the work. Available attendance arrangements and any interruptions should be agreed with the site before testing. Discuss your school’s requirements.
What records will we receive?
Reporting is agreed with the scope and may include asset or circuit registers, test results, defects and completed actions. View the sample RCD report.
How are testing intervals determined?
Intervals depend on the equipment, its use and environment, applicable requirements and maintenance arrangements. Read our test and tag frequency guidance.
What does an electrical maintenance case study show?
The site, scope, testing or maintenance work, recorded results and outstanding follow-up. Results are reported within the scope of the work performed.
Does a testing report mean every defect has been repaired?
Testing identifies the condition at the time of assessment. Failed results require appropriate action, and repair completion and retesting should be documented separately.
Can you help plan ongoing RCD testing?
Yes. The program should consider the device, operating environment, manufacturer’s instructions and applicable maintenance requirements. Contact Masters Voice to discuss your site.
Where can I see audio visual projects?
Visit our separate audio visual case studies for meeting rooms, school PA systems, venues and other AV projects.
