Which CU?

Hager also do a range of metal CU's, the Metal 10 100A 6 way is 219mm wide. Cost circa £50.

excessively bulky. Needs to house 6 MCBs, split would be a plus. Already ha ve lots of Hager MCBs stocked, which I gather fit... I can't find my notes, that's a bit of a problem. IIRC they fit several brands. Contactum & MK ar e listed on the wiki, but there were many more brands they fit as well.

nice & spacious. And metal not plastic. Absolute max width 11.5", 11" would be better. Oh, and the world for sixpence. Any suggestions?

That was the first thing I looked at. Seller said 'Exact width 29.8 cm heig ht 24.5 and depth at deepest point i.e. Including front cover 9.8cm'. Where are you seeing one 219mm wide?

It doesn't show a picture of the unit open, so hard to be sure but I suspec t I know what the problem is. I bet it has 6 ways after the 100A switch is in, 4 of those would be taken up by 2x RCDs leaving only 2 ways for MCBs.

I looked at Hager's pdfs for metal CUs and they were remarkably unhelpful. A table of dimensions with no decipherable information as to what CU each s et applied to! Why so many sellers don't include the basic necessary inform ation I'll never know.

Unfortunately I haven't found anywhere near here that sells Hagers yet.

NT

TLC sell them, but there may not be a branch near you.

Why not use RCBOs which are only 1 unit wide?

wE

no. Their range doesn't include any size suitable anyway. 2,3,4 & 14 ways.

NT

That would work. But 6 RCBOs + enclosure comes to about £200. Bit pric ey.

Would a CU mounted turned 90 degrees pass an EICR?

NT

Would two CUs mounted one above the other (or elsewhere) work?

You just need to decode what they have written!

All CUs have a CU size next to them and the size is given on pages 22 to

1. A bit s*it but the sizes are there.

I was going to say "inches my arse" but I am not that way inclined:-).

Yes.

Plenty of 3ph boards have horizontal MCBs

But don't the electrons fall out of the main switch if that is not vertical?

I think you copied the link below the full catalogue at

The weird thing is the way for Design 10 & 30 CUs they gives dimensions for the "enclosure size" (4, 5, 6 etc) leaving you to look back at earlier pages to see what that means in terms of modules (and AFAICS guess that size 2 = 4 mod and 3 = 6).

ARW formulated the question :

No they seal the bottom of the board to prevent that.

To be fair I did say it was a bit s*it:-) As did NT.

And a lot of Hager stuff is stamped with "Made in France" on it.

Why not "Fabriqué en France"?

same problem though. 2x RCDs would eat up 4 of those 6 ways.
