hi
on the 2391 practical when doind the first test, continuity of circuit protective conductors can i take out the phase conductor for the circuit under test and put it into the earth bar thus getting the R1+R2 aswell to save time?
main question though is do i have to disconnect any other earths from the main earth terminal before doing this?
such as the main earth or supp bonding? bit confused on the parralel paths subject.
at what point do i disconnect earths and for what earths and for what reason?
cheers guys.
