What do we need RCDs fit anyway...

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.

I guess we all work to different standards.

I work to BS7671.

given the choice :
1. isolate the affected circuits and leave customer with a partially -working installation. defrosted freezer?
2. leave in an unsafe condition. dangerous
3. improve the safety by fitting a different make of RCD till i can get the correct one. safely working installation.

i know what i'd do. option 3 every time.

What would you have done?

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?)

Chris,
Volex is an old electrium brand, the mouldings are the same as wylex, crabtree and even marbo.
Although technically it is 'mixing' brands they are all Siemens behind the label.
A crabtree lifestar rcd or a wylex lifeline rcd would be more than adequate for a replacement.

Quite a selection come up on ebay. 20 seconds asking Google works wonders.
