NVQ 2346

Electrical Maintenance

NVQ 2346-03 Level 3 Electrotechnical Experienced Worker Qualification – Electrical Maintenance

The NVQ 2346-03 in Electrical Maintenance replaces the NVQ 2356-99 as the new Experienced Worker Route to the Level 3 qualification – and ECS Gold Card eligibility.

There are five Level 3 Performance Units (see details below) to be assessed before you can gain the Experienced Worker qualification.

Candidates must have a minimum of five years experience and complete both Skills Scan and Candidate Background Forms before commencement to assess their previous/current experience.

Once a candidate has gained the qualification, along with their BS 7671:2018 IET Wiring Regulations 18th Edition and a recognised Level 3 award in Initial Verification and Certification of Electrical Installation, they will then be able to take the AM2E Practical Assessment at any AM2 centre in the UK.

Upon successful completion of the NVQ 2346 and AM2E candidates will be eligible for their ECS card & JIB Grading.
