- Residual Current Devices (RCD)
- A RCD must protect all electrical circuits (static and portable equipment).
- Test and Tag
- Portable RCD must be tested by the user prior to use.
- Damaged or defective electrical equipment (equipment without guarding, exposed wires) must be tagged “out of service” and immediately reported to the Supervisor. The equipment must not be used until the issue has been rectified.
- Live Electrical Equipment
- Working on live electrical equipment and infrastructure is prohibited, except in circumstances where fault finding, testing and commissioning work or electrical supply cannot be interrupted.
- Isolation and Testing for Dead
- All isolation points must be clearly identified, proven, tagged, locked and controlled to prevent inadvertent energising.
- A test for dead (not live) must be completed:
- Prior to or recommencing work on any electrical equipment.
- Following any time away from the work.
- Following changed conditions.
Note: Unless tested for dead, all wires and electrical equipment must be considered live.
- Exclusion Zones
- Exclusion zones must be maintained when working in the vicinity of overhead electric lines or live electrical infrastructure.
