Sample questions
01Where the specification and intended application of an IT cable are not known, what minimum separation from power cables in free air does BS 7671 Annex A444 give?
- A130 mm
- B200 mm
- C300 mm
- D50 mm
Why: Annex A444 (A444.4) gives 200 mm in free air where the IT cable specification or application is not available. Table A444.1 reduces this to 150 mm with perforated metallic containment on the power cabling, and to no extra separation with solid metallic containment. 130 mm is the separation from discharge lamps in Regulation 444.6.2.
02Which tool is essential for proper cable termination?
- AWire strippers
- BCable tester
- CTone generator
- DPunch-down tool
Why: A punch-down tool is essential for properly terminating cables into punch-down blocks and patch panels with the correct tension.
03What sets how far the pairs may be untwisted when terminating Category 6 cable?
- AThe maker's instructions, within the Category limit
- BWhatever leaves the termination looking tidy
- CNothing: untwisting has no effect on performance
- DBS 7671, which gives one limit for every data connector
Why: Keep the twist as close to the IDC as the connector manufacturer's instructions require; the cabling standard for the Category sets the limit. Untwisting too far raises NEXT and degrades return loss. BS 7671 does not set a data connector untwist limit.
