Disconect Main Earth. Put meter across Earth incoming (met) Connect other leads to Phase conductors do test. Then connect Earth and Neutral test leads together and connect to neutral phase conductor, connect the other lead to Line Phase conductor.
Test again. Wich ever is the highest reading in Ka record that on the test results.
Don't forget to re connect the main Met.
All these tests done with power on cons unit OFF
You could also buy Guidance Notes 3 it will help you with all aspects of Testing & Inspecting
take a Ze reading.
230v divided by your Ze reading. then divide this answer by 1000.
Thats your fault current.
Ohms law.

I dont understand. surely V=IROhms law applies to DC supply & not AC
although the ballpark figure won't be far off, it still isn't entirely accurate
saying V=I.R is fine, for DC theory
it is 100% correct, but i assure this is the formula for DC. when considering AC it becomes complex when you have to consider much more, ie. impedance, frequency, reactance, inductance etc.
