On a TT system what should be recorded in the max Zs field when a TT system is employed as obviously the standard values out of the regs cannot be met and thus an RCD is used, however if you record measured as say 37.2 ohms and in max 1.44 ohms it looks stupid. Some of told me you put the max zs as the max EFLI for the type of RCD used. (TT system) are considered to be met when the measured value of Zs does not exceed 80% of the applicable maximum value (such as that given in Tables 41.2, 41.3 and 41.4 of BS 7671). Tables 1 and 2 of this pocket guide give maximum measured values of Zs for fuses and circuit-breakers or the overcurrent characteristic of RCBOs, equal to 80% yep, max. Zs on TT is 1667ohms.

Zs allowed. but as we have all said RCD is necessary.to achieve disconnectin time of 0.2sec. From Table B6 of the OSG, the maximum measured Z s value is1.75 Ω at an ambient temperature of 10 o C. From Table B8 of the OSG, the correction factor is 1.06. Therefore the maximum measured = 1.75 Ω 1.04 You would normally use an RCD for fault protection due to earth rod resistance causing higher than max Zs on final circuits as well as additional protection.

Tables 1 and 2 of this pocket guide give maximum measured values of Zs for fuses and circuit-breakers or the overcurrent characteristic of RCBOs, equal to 80% 07/10/2020 Max disconnection time on a TT system is 0.2sec this is achieved by a 30ma RCD. On some older installations I've seen they would install a 100ma time delayed main switch RCD which would also cover say the lighting circuits and a 30ma RCD on the socket circuits. 2 1.
