Common Mistakes
Common errors to avoid in your coursework
- Not checking resources against specification.
- Overlooking health and safety requirements.
- Poor time management leading to delays.
- Misconception: 'You don't need to follow manufacturer instructions if you have experience.' Correction: Manufacturer instructions are critical for warranty, safety, and compliance; always refer to them.
- Misconception: 'Testing is only required at the end of the job.' Correction: Testing should be carried out at each stage (e.g., after cable installation, before connection) to identify faults early.
- Misconception: 'All cables are the same; just use whatever is available.' Correction: Cables must be selected based on current rating, insulation type, and environmental conditions as per BS 7671.
