    ring main query

    hi all i want to know if its possible to obtain r1 and rn and r2 results by calculation by only having the R2 reading and zs reading i am unsure if this is possible any pointers would be great for a ring main circuit, i can judge the approximate length if this is a required factor

    R2 test on a ring main where the conduit is the earth

    What readings would expect for the wandering lead method whilst testing from the consumer unit to the sockets, would you expect in the region of less than 0.10 ohm?

    Ring main not originating in the DB.

    It's obviously not good practice, but is there a specific reg prohibiting a 4mm from the board to a remote rcd a few metres away, & then a 2.5mm ring from the rcd, round the sockets then back to the rcd. I've come across it on a PIR, and unsure whether to pull it up or not. Thanks Andy
