You will learn more by building it than you will ever learn by using it to carry out tests
Beg to differ. You can do all of the tests on it. Additionally you can put in a bridge in the ring final and see how this affects the resistance results. As resistors are built in to replicate 20m or 30m runs then it is very accuate. Getting into teh correct way of joining earth and phase together and testing is very useful. Additionally, I like learning testing by being hands on and I remember things better by taking practical approach. You or others may be different and just prefer books. Horses for courses I suppose.
where will you put it, once it's usefulness runs out?
a) EBAY - loads of students out there.
b) What screws on - screw off - use them for installations
c) MDF - a million and one uses for off cuts.
Or, even better, why not actually test the circuits in your house?
My wife keeps on beating me up every time I isolate CU to bridge earth and phase to work out resistance of ring final ring whilst shes watching Hollyoaks
Opinions are opinions. I like my test board (and so do NICEIC!)
