No. They are both methods of verifying the same thing. They are an either/or in any situation, periodic inspection or initial verification.

Worrying question from someone carrying out periodic inspections to be honest.
I only asked because im making my eicr certificate and got my assesment coming this saturday.
Just wanted to make sure the inspector wont say anything when i put n/a
 
Consider as well that it is not always necessary to carry out R1+R2 tests for an EICR. R1+R2 is intended as initial verification prior to energising, as a circuit is already energised then it could be considered redundant. A sensible approach is to carry out R1+R2 tests on an unknown installation with no previous certification available. If a previous EIC or EICR is available then a Zs test is sufficient and compare the result to the previous cert, if the result is identical or close it may be assumed R1+R2 is also satisfactory. R2 tests are useful on lighting circuits with fancy class 1 lights which cannot easily be dropped to access terminations.
You should also get your terminology correct, there is no r1+r2 test, it is R1+R2.
r1 and r2 are ring circuit end to end readings.
 
These test are carried out an a new instalation. I wantrd to ask what i should regarding the main supply overcurrent protective devise as it is sealed and not visable is it ok to put limitaion or should i contact uk power to find out ?

Might not be seeing the picture right. Looks like a resin sealed head to me. Are you saying it is a hinged cast enclosure that is wire sealed ?
I beleve so as i forgot to check the writing on the enclosure. Will go back in a few days to check if it has any fure rating written on it

Yeah, that's a WT Henley ironclad service cutout (ISCO) with an ironclad sealing chamber beneath.
Originally it would have been double pole fused, but hopefully someone has put a solid link in the neutral by now!
