Now the competencies combine: mark out, fix conduit and trunking, draw in cables, mount boxes, and terminate. Terminations make or break an installation — strip to the right length, no copper showing, conductor fully under the clamp, screw torqued firm, then tug-test every one. Loose terminations are the number-one cause of electrical fires: they heat, oxidise, heat more, and one night they glow.

1. Mark heights and runs with level and chalk line
2. Fix conduit/trunking every 0.5–0.8 m
3. Draw cables — no joints inside conduit
4. Terminate: strip, insert fully, torque, tug-test
5. Label every circuit at the board
