Terminate cabling and wiring systems

​This standard is about the termination of cabling and wiring systems.
You will need to be able to make terminations according to specification and check they are electrically and mechanically sound using the correct tools and techniques whilst isolating the plant according to procedures and adhering to health, safety and environmental legislation, regulations, and safe working practices.
In the context of this standard, your responsibility is to interpret and work within given specifications, selecting approved methods and techniques to achieve the best possible result. In some cases, you may still be expected to refer to others for final authorisation, even though you remain responsible for identifying and implementing decisions.
Who this standard is for:
Electrical installers and others that install electrical systems and equipment

---

1. ​work safely at all times, complying with health, safety, environmental and other relevant legislation, regulations, guidelines and local rules or procedures
2. ensure that the work environment, material, tools and equipment are suitably prepared for the work activities to be undertaken
3. obtain and interpret the required information and specifications using drawings and other relevant sources
4. identify the correct means of electrical isolation or mechanical isolation of any service/supply/plant/equipment in your area that poses a hazard to your safety and carry out isolation and lock-off
5. prove-dead any isolated supplies
6. make terminations of cabling and wiring to equipment in accordance with specifications and regulations
7. ensure all terminations are complete
8. check the terminations are electrically and mechanically sound
9. ensure terminations are correctly and clearly identified
10. ensure that all relevant electrical equipment, enclosures and components are free from damage as appropriate
11. ensure that the installation is protected from the environment and potential damage
12. check that the terminations are complete and to the required specification, then follow the required handover procedures
