a neighbour of mine has to my surprise passed an electrical course with a training company in town (never heard of them)
to cut a long story short i gets a phone call at 6pm monday night by my local napit inspector asking if i was home/available to come have a chat with neighbour so along i pop to find neighbour having his assessment in the comfort of his living room
i get asked if i know the details of my megger tester as this guy has not purchased one yet and the info needs to be imputted or the assessment cant be completed, guy is in process of buying a tester when he gets paid!
the following questions were being asked
how would you prove isolation?
answer a sketchy 'voltage tester on live terminal then switch off check isolation followed by testing live contacts of switch to prove tester not faulty'
how would you find the pfc?
no idea
how would you test the Ze?
at the meter
you mean at the incoming supply?
yes with my tester
can you describe how you would do this?
no, ive never done it before
do you know what the difference is between Ze and Zs?
ones the incoming reading the other is the circuit reading
which is which?
cant remember
what system is this?
(shows tncs diagram)
tns?
no try again
tncs?
correct and this is?
(shows tt diagram)
is that the one with an electrode?
how would you test an electrode?
no idea
the list went on and on, the guy has been a industrial engineer of some kind but clearly has no idea of testing but has completed his inspection and testing course
finally
no problem, you need to brush up on some things but .....welcome on board!...
speechless.....
(he is enrolled as domestic installer and for pv)
half of me wants to complain th napit half is thinking whats the point really....
