Hi, Doing 2395 revision and doing a small temp builders supply therefore TT . Installed 2 x 13a sockets protected by 16amp breaker and 30ma RCD.
Installed 1 x earth rod immediately by the meter / con-unit position. No other circuits. No additional main equipotential bonding as nothing there.
My Ra (Ze) reading was 10 ohms using an ELI tester method 3 BGB. I'm under the impression that this reading is OK as under 21 ohms but I'm unable to find this figure in writing. But reading other threads I see figures of 200 ohms. The figure of MAX 1667 ohms baffles me for 30ma RCD. RaIn<50v. Clarification required please. Apologies in advance as I'm sure this subject has been flogged to death on here.
