Year 1 Dashboard

We are currently in the Term Break between Term 2 and Term 3.

Enjoy the break!

Use this time to recharge and catch up on any outstanding work from Term 2.

Looking Ahead

Term 3 commences on Monday, 20th July.

When we return, we will be moving into Unit 32614: Electrical Faults, Circuit Protection, Decommissioning and Commissioning.

• Ensure your gear is ready.
• Keep an eye on the LMS for any official updates.
• We’ll see you back in class on the 20th.

Last week in virtual night class, we worked through the EE401.19 pre-course session for the Year One Block Course, linked to Unit Standard 29749. The focus was on preparing for the first four block course tasks and identifying the areas learners may need to practise before attending.

Course Structure & Framework

We covered the block course structure, including:

• The EWRB stages framework.
• The seven assessed tasks.
• The concept of staircased learning.

Pro Tip: Speak with your employers about the skills covered so you can get some practical experience on site before the course.

Technical Revision Areas

1. Circuit Protection

We reviewed common protection devices:

• MCBs, RCDs, and RCBOs.
• HRC fuses and rewirable fuses.
• Motor overloads.
• Key Reminder: Rewirable fuses cannot be newly installed.

2. Fault Types

The three main faults we focused on:

• Overload
• Short Circuit
• Earth Leakage

3. Cables & Fittings

Overview of various types including:

• TPS, flexible cords, and neutral screened cable.
• SWA, fire-rated cable, and data cable.
• Socket outlets, lighting fittings, conduits, and protective fittings.

4. Terminations: Crimping & Soldering

• Emphasis on correct lug selection and using the correct crimping tools.
• Safe termination practices.
• How to recognise poor solder joints.

5. Extension Leads

• Plug top types and current ratings.
• Cable selection and polarity.
• Three-phase plug configurations and common faults.

6. Appliance Testing (AS/NZS 3760)

We walked through the testing sequence:

1. Visual inspection.
2. Earth continuity.
3. Insulation resistance.
4. Polarity testing.
5. Tagging and recording results.

Safety First

We reinforced critical safe testing habits:

• Test Before Touch: Always verify your environment.
• Prove-Test-Prove: The essential sequence for verifying your test equipment is working.
• Sequence: The AS/NZS 3760 testing sequence must be followed strictly in order.
