Mark out materials to the required specification
Overview
This standard is about marking out to the required specification within the occupation of electrical installation.
You will need to be able to mark out materials to specification as part of a
standard preparation prior to undertaking electrical installation activities 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 and clearly defined procedures, selecting appropriate techniques. 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
