UNIT 110

Introduction

On this page we walk you through everything you need to know to get started – and complete – Unit 110 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.

   6. Servicing records
   7. Manufacturer’s instructions
   8. Certificates of competency
   9. Permits to work
   10. Other relevant information
9. Verify that proposed materials / equipment / components are in accordance with:
