probably as it's a TT earthing system. a rough idea of when it was installed, has it got any 30mA RCDs?
 
there is a 30mA Rcd half way down the bus
would this setup be acceptable for eicar or unsatisfactory?
also, there are two breakers which are lableled cooker and central heating, these are unused the wires go nowhere, , its lagacy of old house, cooker and ch are on kitchen ring now
should it fail eicar for this?

So it controls nothing? Why would it be a fail on an EICR?
 
worked in telcomms for many years matey, well up on electrics and hands on eletronics but not familiar with this stuff, dont worry im not diy, just wanna know exactly whats going on and dont wanna be taken for a ride by the bloke who failed my eicar,
 
No he is not taking the pee

Unable to trace final circuit... if he has it as a c2 its a fail, c3 then not, i thought it was c2 but im not 100% sure, hence the edit

Fail.. End of story

cmp, you really need to explain what you have a bit clearer....

a 100mA RCD main switch feeding a few MCBs and a 30mA RCD which then feeds the remainder of the MCBs?

Nothing obvious wrong with that so far.
2 MCBs where the "wires go nowhere". So their are cables to these MCBs? where does the other end go to? is it terminated properly?
If this isn't clear then I'd put it down as needing more investigation.

You appear to be implying that someone has done an EICR as unsatisfactory. If this is the case what are the codes and comments?

EDIT: oops, Murdoch can type faster ;)
