Hi Mate
here are some things to help your remember stuff
Periodic inspection you are looking for a SADCOW. issues of Safety. Ageing, Deterioration. Corrosion, Overloading, Wear and Tear.
Also Insulation resistance is like a teabag the longer the cable the more perferations so more area to leak out of hence Insulation resistance decreases with length.
Cable resistance is like linking sausages togethr the longer the length the more sausages you have so greater resistance
Also learn the proper terminology for protective conductors. See little map at end of appdx 2
Circuit protective conductors connect to exposed conductive parts to MET. Exposed parts of electrical equpt motors lights etc
Main protective bonding connects gas and water Extraneoues conductive parts to MET. Any EXTRA METAL is Extraneous
Earthing conductor connected between MET and earth electrode
Hope this helps
