Practical consists of 4 assessments:
1 - a 2 hour inspection and test on a double rig with all documentation to be completed, things like safe isolation procedure, test sequencing and safe obtaining of live tests to be observed.
2 - a 20 minute insulation resistance test, where 2 faults are switched into the rig and you need to identify the designation of the fault, along with the fault type.
3 - a 10 minute earth fault loop impedance (Zs) test where you carry out 2 tests, then compare with the OSG as to wether the reading is a pass or fail.
4 - a 30 minute inspection test where you look at a rig which has had a number of faults, irregularities introduced and you need to observe, and report your finding. A particular 12 are to be found.
These are the practical assessments as we are told by C&G to set them.
So when are you sitting the practicals?
