2core swa, not earth load end.. TT

[Wilko]

However the OP was asking about R1/R2 vis a vis the garage assuming I read it right I am tired and somewhat sanguine tonight.

I'm just into the 2nd glass

Jesus this is over complicated. He cannot verify continuity of the armour because it has been rendered inaccessible.

 

[The Ghost]

would I note this down as the garage r1/r2 circuit. Accepted with the 1667ohms as rcd?

The question seems to be about the garage unit

this is over complicated. He cannot verify continuity of the armour

Not the armour???

Wasn't confusing at all Robo.

I think I'll leave this subject for now night night.

His initial problem was not being to access the armour of the supply cable to verify continuity and could he record the TT results for the supply cable, answer, no.

 

[driverman]

Not that I'm into testing.....Could not the OP measure the TN Zs at incoming SWA cable at garage consumer-unit? Note reading and subject that reading from the Ze reading obtained at the house consumer unit giving R1-R2.
Another way...use Method 2 wandering lead, assuming connection can be made onto the end of the SWA armouring using a probe.

The final connection of the armour is not accessible.
