Selecting and preparing materials and components for electrical assembly

​

This standard identifies the competences you need to select and prepare materials and components for electrical assembly and wiring work, on electrical distribution equipment, switchgear or control systems, in accordance with approved procedures. You will be expected to identify which materials and components are needed, to obtain them in the quantities required, to check their condition, review the need for and undertake any specific treatments or preparatory actions which may be required.

Your responsibilities will require you to comply with organisational policy and procedures for the material selection and preparation activities undertaken and to report any problems with the activities, materials, components or equipment that you cannot personally resolve, or are outside your permitted authority, to the relevant people. You will be expected to work with a minimum of supervision, taking personal responsibility for your own actions and for the quality and accuracy of the work that you carry out.

Your underpinning knowledge will provide a good understanding of your work and will provide an informed approach to applying material selection and preparation procedures prior to electrical assembly activities. You will be expected to know about specific material characteristics, in sufficient depth to determine if the materials are suitable for the intended application. You will understand the preparations required to be carried out on the materials, in order to ensure that they are ready for the assembly activities. You will understand the work requirement and its application and will know about the overall manufacturing operations, in adequate depth to provide a sound basis for carrying out the preparation activities to the required specification.

You will understand the safety precautions required when preparing the materials and you will be aware of potential hazards and how to minimise the associated risks.  You will be expected to apply safe working practices at all times and you will understand the responsibility you owe to yourself and others in the workplace.
