Hi,
I have been round my friends house as he has a TT system and I have never worked on these installations before. (yeah yeah, pathetic I am! lol)
Whilst doing the PFC the result was 11 Amps.
Is this correct for a TT system?
I am guessing it is as the Ze was 20.9 ohms.
I was just expecting similar readings to a TNS system where it is above 1KA.
Guess this is the reason TT supplys (I know all do now to the 17th) needed time delayed RCD's to the 16th edition
Thanks
