218.5(Uo) / 160 (la) = 1.36525 (rounded to 1.37) Maximum Zs Value Step 2 above shows the voltage to earth after applying the 0.95 Cmin factor. The 1.37 ohms value is the 100% max Zs value which should be recorded on the test certificate.
Biowash - provides extremely soft hand feel. Maximum Zs values in a TT earthing system The maximum disconnection times for a TT system is 0.2 seconds for final circuits up to and including 32A (Table 41.1) and for distribution circuits or circuits greater than 32A it’s 1 second (411.3.2.4). 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.

The Zs values in that table are intended for a TT system but may also be applied to a TN system. Bs7671 state that max permitted Ze for TT is up to 200 ohms. I've drooped to 14 ohms by installing 3 earth rods. Question is when you doing measure Zs what is the max permitted for each MCB 6,10,16,20? Can anyone help please Max Zs values for Android devices, look up the maximum permitted Zs values (earth loop impedance) as per BS 7671 18th edition. Max Zs values include 100% (BS 7671) and 80% (On site guide) 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 Just starting to look into TT systems a little more.

If you go table 41.5 in the regs it gives you the values of Zs for a T.T. installation. It all depends on the RCD in use i.e from a 30mA (1667 ohms) to a 500mA (100 ohms). It then warns you in a note below the table that the rod resistance shouldn't be above 200 ohms because it could be unstable. (The NICEIC ask for a 100 ohms)
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. that's what you put on the test sheet as max. Zs allowed. but as we have all said RCD is necessary.to achieve disconnectin time of 0.2sec. Mar 24, 2018 · For RCDs not covered by Table 41.5, the maximum value of Ze can be determined from information given in Table 3A in Appendix 3 of BS 7671, by using the formula given on the same page as that table. In addition, for a TT system, Zs must be low enough to meet the condition RA × I∆n ≤ 50 V, mentioned above.

If you are using RCBOs on circuits requiring 30mA protection and a selective type on the incoming it is 150 to 500ms on circuits without the RCBOs, so even worse.
