Scenario
You are part of a solar PV technical team preparing a completed Solar PV installation for inspection, testing, fault finding, and commissioning activities. Before testing and commissioning can begin, all system components, protection systems, monitoring equipment, installation materials, and work areas must be inspected and verified according to workplace operational standards and electrical compliance requirements.
You are required to prepare the operational environment safely, identify hazards, inspect Solar PV system components, and ensure operational readiness before testing and commissioning activities begin.
Instructions
