Temporary supplies, live-work avoidance, competent isolation, service location, inspection and damaged equipment.
How to prepare for SMSTS

Core concepts
Concept 1
Electrical work should be dead where practicable and controlled by competent isolation and verification.
Exam cue: Identify all energy sources and prevent reconnection.
Concept 2
Temporary supplies, distribution, cables and tools must suit site conditions and be inspected and maintained.
Exam cue: Protect cables and equipment from water, impact and traffic.
Concept 3
Plans alone do not prove a buried or overhead service position; work needs suitable detection and safe systems.
Exam cue: Withdraw defective equipment from use.
