This standard is about positioning and installing electrical equipment and systems in engineering construction plant

You will need to be able to install and position electrical equipment and systems by following engineering drawings and specifications whilst 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
This standard is for electrical maintenance technicians and those that maintain electrical plant and equipment.
