Is it a 2 or 4 Pole RCD?

It does say that it is a replacement from an MK bod on the Q&A part and can be used to replace the existing one. But not to worry you can always split the tails to a henley block and put an RCD for something else like garage etc. independently. Sure your chosen spark will tell you of this alternative.

No that's a 63a, the original 4 module RCD is 80A rated.

No .......... then its how can I do this? My spark is on holiday? My spark is asking me to buy .................

Cynical - maybe .............. but so often happens...............

I agree, I know a lot of them are doing it themselves

That is not an equivalent. That is 63A. The existing is 80A.

Damaging? It can only serve to improve the forum if it discourages diyers from posting.

I have to disagree with you here mate. We have a DIY section to help them out. We just can't give out step-by-step instructions. It is up to each forum member if they want to help or not. Simple.

I just wanted advice as if it can't be done I'll need to cost up a CU replacement with my spark!

As @Vortigern has already mentioned. If the RCD can't be replaced your electrician could add another small CU next to the existing one. This can feed the garage.

I guess a few forum members have had a bad week to be this tetchy on a Friday.

To change the 4-module sized RCD to one that only takes up 2 would mean sourcing another busbar that feeds the MCBs. The one you have will be 2 pins short.
The idea of Henley blocks on the tails to feed a separate RCD isolating switch to supply the new outside installation is the sensible choice.

I think Murdoch was merely pointing out that its a new circuit addition and changes to cu so basically make sure you get a spark in? Just... Kinda like a note.

Thanks all, some very sensible advice and just to re-iterate I'm not doing this myself. I've spoken to my spark and the wheels are in motion for a professional and most importantly safe installation.

 

[TJ Anderson]

After your discussion, what have you decided to actually do then?

 

[Sintra]

@Jon7 We have given you diy status and moved your thread to the diy section of the forum as this section of the forum is for members that will give you constructive advice.

You can buy a 2 pole MK RCD, a new bit of bus bar and a split load kit that will give a flexible neutral link cable. Get an electrician to do it though, it’s not a DIY job

First of all I didn't want to start any arguments so apologies for this

I dunno, somebody comes to the forum to seek some guidance, then ends up trying to break up a fight, and then apologies for starting it
