  • Building Regulations.

Learning Outcomes

This unit is comprised of the following FOUR Learning Outcomes – full details below.

LO1 – Prepare to install wiring systems, enclosures and associated equipment
LO2 – Interpret appropriate information for the installation of wiring systems, enclosures and associated equipment
LO3 – Install wiring systems, and equipment in accordance with current relevant statutory and non-statutory regulations
LO4 – Confirm the quality of the completed work

Evidence Requirements

For Learning Outcomes 1-4

Auditable evidence sourced from a real working environment must be provided to illustrate that you have demonstrated on two separate occasions, that you can apply design procedures, for the installation of electrical systems and equipment, in accordance with the assessment criteria.

In the delivery of this unit, an emphasis shall be made on the necessity to keep up to date with the latest standards, technologies and practices which relate to and affect the topics covered in this unit. This is then in keeping with good engineering practice.

You personally should be in as many photos/videos as possible.

Unit 109 – Apply Design and Installation Practices and Procedures

Introduction

On this page we walk you through everything you need to know to get started – and complete – Unit 109 of your 2346 EWA

What is Assessment Criteria?

This is the criteria you are being assessed against. In order to successfully complete the assessment, you must meet the criteria in EVERY unit.

How do I meet the Assessment Criteria of every unit?

You will simply provide evidence (photos) of HOW you carried out your duties.

This unit is about you working safely whilst carrying out your electrical installation or maintenance duties. You must provide evidence that you have carried out a risk assessment BEFORE you started work, review your working area DURING your working day, and tidied up upon completion of the job. You need to demonstrate that you have used access equipment safely and are dressed in the appropriate PPE.

See an overview of this unit’s assessment criteria and examples of evidence below.

You need to be in the Photos.
