[QUOTE="Mr T, post: 92327, member: 5649"] Things that will most likely be in your exam Tabulated values of ZS and then applying the rule of thumb i.e. x0.8 to get a more true reading , it takes into account the ambient temperature of the cable in load conditions.. Draw an earth fault loop path diagram and lable it.. practice all earthing systems.. know your statutory and non statutory regs... know the relationship between resistance i.e. CSA and length and what heat does to the resistance Know what test equipment to use for each test Use diagrams instead of explaining , handy for your r1,rn and r2 and crossover tests on ring finals... Know the basics of an earth electrode resistance test Know that to regards PEFC and PSCC tests and which result to note and what to do on a 3 phase installation Know the inspectors responsibilities and the purpose of Installations and Periodic Inspection Reports.. When they say 'state' 1 statutory document you answer Electricity at Work Regulations 1989 If a question with the term 'state' in can be answered in 1 word then thats how you should answer it.. Learn the model forms off by heart , especially schedule of inspections [/QUOTE]
