Discuss Very Hi ZS Reading on TT system? any advice in the Australia area at ElectriciansForums.net
ZE was 187
the system is protected by a 30ma RCD from the main house, and the new board is also protected by a 30 ma RCD.
??
ZE reading 187ohm
I can determine ZS by enquiry, ZE +R1 +R2 = ZS
However, i tried to test and measure ZS at the end of the circuit and got these high figures of 2.6 2.5 etc etc...
again, any ideas on how to solve this issue???
Thanks

would that be a 30mA RCD protecting the sub main and another 30mA RCD protecting the final circuits in the outbuilding i.e. 2 RCD's in series
I was too slow in replying to specialist (too slow, specialist beat me) sorry to cause confusion
i can feel discrimination entering the fray here!!..lol....ZE was 187

and if you are going to start driving more rods in...then go for depth every time ...."depth is the key with TT".....
