What would you put on report?

[Doomed]

Testing a premises and all the older installation has its earthing only through the metal conduit / trunking.
I get good results on both the r1+r2 and the Zs results, but as there is no actual CPC what do I put on the report?
Thanks for your advice.

An R1+R2 on a conduit installation can usually only be obtained when its under construction

Just note the conduit is used as the circuit protective conductor on the cert not alot else you can do , as long as the conduit is in a good condition and not broken , it only becomes a problem if its added to or altered especially if its done in plastic

The conduit is the CPC.
Testing the R1 + R2, whilst under construction, is for when there is a separate CPC contained in the conduit.

On a metal containment where the metal is the CPC, for a PIR I would only be doing the R2 test to be honest.

I'm hoping that you just mean how do you show the trunking or conduit as a CPC on your schedule rather than not knowing if it complies or not.

Just enter 'Trun' or 'Con' in the CPC box on the schedule of test results.

AMTEK ahen you put cable sizes on the CPC it has ARM,CON,Trunk,MICC and then a popup with sizes in mm for what ever size you put in
