You've lost me.

rules and regulations can be determined in different ways, depends how good a lawyer you are

 

[davewdave]

yes you can have a front end rcd protecting all your circuits acting as a main switch... i think thats what you are asking

On an existing install yes, as a new or rewire or new CU installation - no

What's the difference between them then??

existing installl means a cu in place with a single RCD. i.e. no changes being made to the cu

Click 'new thread' on a relevant forum.

It's a big blue button in the top left hand-corner, it's literally unmissable.

Use a PC or Laptop - using a mobile is a waste of time.

Are you saying, i can't for arguments sake have an S type 100 mA RCD replacing the CU's main isolator switch on say a TT system?? Personally i can't see a problem with it, be it an existing CU or new 17th ed CU, the DP switch mechanism will conform to the same requirements as the normal isolator switch...

rcds are not for overcurrent so you are relieing on the breakers for that, and are all rcds not douple pole......just asking because im ****, not trying to tell anyone the way
