Are there any reasons to choose one make over another?
I need a split amd3 board with one section RCD protected, one section of
RCBOs and a few unprotected MCBs for sheds and other things with their
own RCDs - probably a total of 14 circuits. Without any reason to choose
a particular manufacturer I'm drawn towards MK because I've got a few MK
MCBs - is there a good reason to choose a different manufacturer?

I chose MK recently, purely on the basis that I have never been let down
by their gear.

It may be better value to buy one of the pre-populated ones?

Hager is very solid and the range of devices is excellent. Also you are
less likely to find you can't buy a new MCB or RCBO that fits (properly)
in 10 years time like one crap brand I had dealings with.

If you can stump up the dosh, consider going all RCBOs - it's a superior
system to a couple of RCDs.

You can't have "unprotected" MCBs for anything much now - all sockets
need to be RCD protected and unless you are cunning with the cabling,
the routing of that tends to demand RCD protection.


One thing you could consider (what I did) as 14 circuits is a lot and
clearly some of yours are external:

Take a 40A +/- RCBO circuit to a secondary CU nearer where your external
circuits go (possibly even an external building if that makes sense to
run on from there) and populate that with MCBs.

Keeps the clutter down in the main CU and does save a bit of dosh by
putting several non critical external circuits on one RCBO.

Of course, if you have critical stuff outside (eg freezer) this makes no
sense...

BTW Did you recheck the tightness of your terminals on your CU?

Hmm I've now seen other recommendations for Hager and a few negative
comments about MK - I'll investigate further.

The plan is to put the critical stuff on RCBOs, but I'll look at the
cost difference with Hager.

Understood, but the sheds and car charger all have their own RCDs.

I'm trying to do the opposite. At the moment I have two sub mains from
the garage to old Wylex fuseboards (one for lighting and one for
sockets) in the centre of the house, plus a whole bunch of small CUs in
the garage. I want to consolidate the whole mess into one location:
probably one CU for the house and a second one for the garage, workshop,
sheds and outside sockets.

Because of the number of radial circuits the pre-pop units don't have
the mix I need

I did, and they were good and tight. I suspect that means I grossly
overtightened them the first time round.

Indeed - there is no right and wrong here.

My CU was a bit full (I like to leave gaps between each pair of RCBO for
cooling) and all my external circuits exit from the other side of the
house - so it made sense to put a secondary CU upstairs near the exit point.

I also had to site a small CU over a doorway thanks to EDF's annoying 3m
rule on meter tails...

I don't normally ave anything good to say about American power systems,
but the fecking enormous breaker panels they install does make things
much more pleasant to work with:

There is no is such thing as grossly overtighten-

It just means you did the job properly first time. I consider the extra
time you spent rechecking them to be time well spent.

Nice one.

I've never been an MK fan. Top end prices - but definitely not top end
design. And in terms of looks, well behind many others. And as for
reliability in normal domestic use, not sure there's that much difference
between any reputable brand.

I am not sure if they are the re badged MGCs from CEF or the other way
around. Either way a pile of ****.

The one thing I can say for MK is that at least they make MCBs that
cannot be fitted with the bus bar terminal behind the MCB terminal.

But yet all schools and hospitals around my way always seem to spec MK
stuff (apart from DBs).

Everyone knows the correct way is:

Tighten it until the head snaps off;

Do the replacement up slightly less tight.

Probably because it's the only name the architect knows. Given it's been
around for ever.
