6A RCBO for this Legrand?

[Octopus]

Hoping to save some time on this!

Need a 6A RCBO to fit this Tenby / Legrand board - anyone know if they are readily available?



Thanks

Yes i bought a 40 or 45 the other week. Not cheap but saved messing about.
I think I ordered mine with eddies, but can check if you have trouble ordering one.

City could also get them next day but as normal miles to dear irate:

I queried with Legrand about fitting one of their RCBO's in a similar looking CU as yours. They said it wasn't compatible & won't fit?

Just check what I ordered, & it was from CEF 50A SP+N 1 Module 10kA Type B 30mA RCBO | City Electrical Factors
but by all means double check with Legrand. But the board lookes the same.

Somebody else said something similar hence the thread!

Is this the same DB ? Zoom in to see the 6amp RCBO i have fitted.

The 6a MCB I was thinking of replacing with an RCBO, was a Legrand 06156. Legrand said their current RCBO was incompatible with the CU the 06156 was fitted in. Is that the same MCB as in your CU? Let us know if you find the opposite is true, make my forthcoming job a bit easier.

Yep normally do that myself. However in my particular case, customer is converting existing bedroom into bathroom, and existing bathroom into bedroom, don't ask me why! So new bathroom needs RCD, and existing bathroom pull cord will need converting to normal flush switch. No room at the Inn, where CU is located, but converting mcb - rcbo would have been a good'en.

That's a very poor design, you can't get discrimination between the fuse and the mcb. A better solution is an RCD in a separate enclosure.

More expensive though, when all you after is the additional RCD side, does it matter if the fuse or mcb goes first?

Depends on whether you take pride in doing a job properly, or just want to bodge it and scarper really

It’s not a bodge in my opinion (and that of others I think), just an acceptable method of resolving an issue. Another example, if someone hasn't an rcd protected RFC whilst using an electric lawn mower, then a socket outlet RCD or adaptor could be an acceptable answer.

If all manufacturers produced their products, that had backward capability or indeed bespoke RCBO's to fit into older CU's, then we were not be having this discussion on how to resolve such an issue. To provide an RCD in an enclosure is arguably more expensive to supply & install than a local FCU RCD, balanced against flushing one cable in a wall in a bathroom for example. I don't bodge anything and run, I explain the options available, with the costings and my recommendations and let my customer decide which way they wish to proceed.

One could argue that having more than one CU is a bodge, when the installation should be upgraded to one that complies with all the latest regulations, but then would be just irresponsibly trashing equipment that is still functional.

I’m disappointed by your childish reply; I would have expected a more constructive response from you.
