You have asked this question before in your other guises.Hi do tt earth systems highly require a rcd, and if not are upfront rcds a must in the tt earthing systems? Cheers
I wonder what John is driving at?You have asked this question before in your other guises.
Recent thread, now deleted I think, concern that up front RCD was ‘no longer accessible’.What other guises, just so I can avoid replying?
Well I really needed the info that's why i bought my @ss back in this forum
So basically my question is if a TT earth system has no RCD will a upfront rcd be there behind the consumer bloody unit? Thanks. Need a answer for that only plz
and i blocked up the upfront rcd with tiles so if i trip it that would mean i wont be able to reset it if thats where the upfront rcds are located.
Can someone just tell me that cheers
ok, and do all tt systems have 100 percent a upfront rcd? cheers im nearly done going out of this forum

Yeah thats my question done with cheers everyone however will connecting the main earth with a metal pipe not require any rcds?
And how to check if the main earth is connected to a pipe instead of a rod.

yes mate can you remove this entire thread, i give up. With this thread it might motivate me in touching the cutout fuse so might aswell remove this thread
My concern is that there is apparently considerable uncertainty about whether this installation would disconnect under fault conditions as opposed to sitting there with live metalwork ready to kill someone.
From the questions asked I don’t think we are going to be able to reliably guide the OP to an answer.
This could be a life or death matter and as DPG said the installation really needs looking at asap.
Exactly, without any additional RCD protection and say a Ze of 80 ohms you'd have a dead short live/earth current of around 3 amps, wouldn't worry even a 6a MCB so all the earthed metalwork sits at mains voltage.I've seen TT installations where a fault meant live metalwork - not a fun situation.
Without any intention of causing offence I believe that you have a very poor knowledge of requirements for protection against shock and I strongly advise you to get an Electrician in for safety's sake.yeah true but the lucky man here got earth leakage circuit breakers, but its kind of disappointing to see that as all the pipes are connected with the earth and under a fault condition not all current flows to the elcb as some goes to the other pipes and most luckily they have lower impedance compared to the breaker.
Yeah true here the elcb's still remain fine in the regulations im aware that they dont protect people but rcbos are good upgrade hmm...I've just realised that the OP seems to be based in Africa so I'm not competent to advise, but surely there must be RCD requirements ?!

Well i do both part time dentist and electricianWithout any intention of causing offence I believe that you have a very poor knowledge of requirements for protection against shock and I strongly advise you to get an Electrician in for safety's sake.
That’s got me wondering if your dentist’s drill is earthed and part of the same installation…..!Well i do both part time dentist and electrician
just joking about the dentist mate
im from south africa
also i opened up the tiles and the only thing i saw was full of earth wires???
cheers m8
