How did I do?

Great work, especially neat considering some of the cables were the originals.

Are those solid or stranded conductors to the RCD's? The blue and brown sheath looks loose around them.

I can't believe the great RF didn't clip that white cable going south...

We use Hager, too. Aren't those new blanks monstrous?

Thats an ELV cable for the doorbell. I forgot to get the new trannie, so it will be sorted next time I'm there

AFAIK, hager blanks have always been like that. Well they have as long as I remember anyway

It looks like a PME system (from the appearance of the service fuse unit!) - where are the Main Bonds to gas and water?

Next to the main earth in the bonding terminals of the MET

I love the approved locking off devices in the first picture....

Nah, the previous version of CU had much neater clip-in blanks that fitted onto the cover.

The new ones are much bulkier &, like the MK ones, fit inside the board.

Why change the design, I don't know...

 

[RF Lighting]

I've been using them big chunky blanks since I were knee high to a grasshopper

 

[securespark]

I'm a bit perplexed now!

The old Hager boards we fitted had the clip-in-to-the-cover blanks - I'll post you one if you'd like to eyeball it - and when we moved over to the new Hager boards, the instructions were included,

"not compatible with old Hager blank - use new one..."

if you use the old ones, it distorts the whole cover horribly.

Nice work RF - Hager boards always have plenty of room even when full of RCBO's.

I remember using those big blanks in some TP hager dist boards I fitted in a big pub just after I had served my time, maybe 6 or 7 years ago.

I have seen the small ones like you get with merlin DBs but they never seemed to fit the plastic front of domestic type CUs very well

 

[securespark]

The old style Hager ones are better than most:

They have a very positive fit -

the lower edge has lips that fit either side of the cover and the upper edge has two bendy lugs to ensure a snug fit.

I'd post a piccy, but I can't be bothered to go down to the van & get one...

 

[RF Lighting]

I know the ones you mean, but they never seemed to fit the plastic CU fronts very well IMO.

Right, this is the CU which I fitted when I built my shed about 4 years ago.

Look, it has a big chunky blank

Well confused now. [What do you mean that doesn't take much?]

Oh well.

This is what I call the "new" Hager blank:

And this is what I call the "old" Hager blank. Actually, i think they fit very well, better than all the others I've tried. I use them on most consumer units where I find a hole that needs plugging :
