Putting my own little problem aside, it does open up a wider question. Anyone could have a Merlin Gerin consumer unit and want to replace the components, or add a circuit in a blank space or otherwise change the configuration. If they are to shy away from 2nd hand components with uncertain...

You're right. I don't think I'm even going to bother replacing the MCB. I'll just have to bite the bullet with more detailed investigation. As regards all the ebay stuff being 2nd hand "tat" though (accepting that one would need to be very wary of fakes), all my MCBs are 30+ years old and...

Is a C60 (or C60N) completely compatible? It doesn't seem to use the little fork connectors which the C45 does.

Cheers. half an hour of googling, I just couldn't find that. Yes, BCD not ABC. I just meant there were letters not numbers. I suppose you're right about the MCB too. How could a fault in a single pole MCB trip the RCCB? Unless some current was somehow leaking to earth within the consumer...

I have a (UK domestic, private house) Merlin Gerin consumer unit with Multi9 C45N circuit breakers and I want to replace one of them. When I look for replacements, all the similar ones for sale (ebay mainly since this range appears to be discontinued) seem to be labelled "Type 2" whereas the...

Oh that is good news. Thanks for the explanation. It sounds so simple I'm tempted to it myself now. Is it one of those "Part P" things where I should get a qualified tradesman to do it, or am I allowed to do my own work in this instance?

Great, that sounds good. I was getting the 600mm from basin idea from this earlier thread: //www.diynot.com/forums/viewtopic.php?t=74819&start=0 I've just re-visited it and it is rather confusing, but it does seem to say that the 600mm matters and that the work is notifiable. However...

I have a first floor bathroom with a combined light/shaver socket over a big rectangular mirror. This runs off the lighting circuit, has an integral isolation transformer and is earthed (ie is supplied by a 3 core L/N/E cable). The shaver socket on the light is too high to use (particularly...

The installer was definitely a cowboy. He did a variety of work as part of a bigger domestic refurb contract, never turned up when promised and much of his work needed remedial attention after he'd gone. To be fair, his selection of the Keston C55 for this job was probably an honest mistake...

"kestonaid" is one of a number of results which comes up on google but doesn't look like a genuine firm of heating engineers - more like a call centre trawling for jobs. My Keston has failed a few times over the year. I have had a few new fan assemblies and a new heat exchanger. It seems to...

SW15

Lots of fun but not very helpful. After my experience, I wouldn't buy another Keston. Nor would I employ Keston to do any work. But why should I put a working boiler in a skip and spend my hard-earned brass on a new one when none is required? My old engineer (who appears to have now emigrated...

A lot of the original boiler has been replaced over the years, so to call it 10 years old is a bit of an exaggeration.

I have a 10 year old Keston C55 requiring its annual service. I live in SW London. My regular service engineer (who has done an admirable job for the past few years) now seems to have disappeared. For various reasons, I prefer to go to an independent rather than to Keston. It's difficult to...

Thanks - you've given me some ideas for one or 2 more bits of testing/diagnosis. Can't do these properly until the fault recurs, so I'm going to start leaving the dishwasher switched on at the mains all day again, wait for the fault to recur and then try a few tests. Having read around now on...

Here are some pictures: //www.diynot.com/network/andrewjameshoward/albums/14947. The unit is in a corridor - I cannot get far enough away to get proper focus. The unit is labelled Merlin Gerin AMG15. I believe Schneider took this company over. As far as I can see, everything routes...
