Not sure if there is a specific group for posting things like this?

When your RCD stops working this is a much cheaper remedy to the problem..

This issue was quickly rectified for the customer (correctly)

Right old cock up is that.
 
Shorting out the RCD for continued operation is something I wouldn't have considered as a method of providing a safe electrical environment for the clients...
Do you know why it might be dangerous? DO you drive a vehicle with wheels or legs?
 
Is this bypassing the RCD, or just getting a live to the MCB because the bus bar is too short?
What is that cable covered in black tape in the RCD Neutral?
 
Just to clarify. This is how I found the board, not sure if my sarcasm came over correctly in my post. I hope no one thinks I was suggesting this was actually my remedy.

I have put a new RCD in. It is a temp fix as it is not a Volex RCD as I’m struggling to find a source for a Volex brand? Can anyone suggest a compatible brand or should this be a complete board change if Volex no longer exist (surely not tho?)

The RCD has been bypassed because it wasn’t working so non of the socket circuits were protected.

I found it by chance because I was there to do an unrelated job
 
I would not have done any temp fix with a non compatible device.
I do a lot of call outs for estate agents etc. It's impossible to carry every make, model and size of RCD/RCBO/MCB on the van and sometimes a replacement is 7-10 days away. Would you leave a property without power for 7-10 days, or fit something that fits safely in as a temp fix?
 
The reason we don’t mix and match compatible components in CUs, is because we lose the 16kA type tested breaking capacity.
If the individual breaking capacity of the individual components is greater than the PFC, there is no reason why they can’t mixed and matched.

In this particular instance the components have already been mixed and matched, so the 16kA type tested breaking capacity has already been lost.
As such adding another component to the mix will not make the installation any less safe and will improve safety by providing RCD protection to the sockets.
