Sample questions
01Documentation of fault finding should include:
- AThe date of the visit and the hours worked on site
- BOnly the final invoice amount charged
- CThe make and model of the faulty equipment alone
- DSymptoms, tests performed, fault found, and repair made
Why: Complete documentation includes the reported symptoms, tests conducted, fault diagnosis, repairs made, and verification tests performed.
02Why is documenting test results during fault finding important?
- AIt records the work and evidences proper testing
- BIt guarantees the same fault will never recur
- CIt is only needed for three-phase installations
- DIt removes the need to retest the circuit after repair
Why: Documentation provides evidence of proper procedures, assists future fault diagnosis, and may be needed for warranty or legal purposes.
03A Minor Electrical Installation Works Certificate is appropriate after:
- AA full new installation in a domestic property
- BA periodic inspection of an existing installation
- CAdditions or alterations not requiring new circuits
- DThe installation of a complete new consumer unit
Why: Minor works certificates are for additions or alterations that don't need a new circuit - many fault repairs may fall outside this and require different documentation.
