Consumer unit area

[Iggifer]

Dunno. Is it type-tested to EN 60439-3?

Clever clogs!

i hate to join in, but what's an enclosure that contains MCBs and cartridge fuse carriers in one called?

How about "consumer unit"?

 

[ban-all-sheds]

p.s. you should NOT really have MCBS and cartridge fuses on the same din-rail

Why not?

AND THAT IS NOT A RHETORICAL QUESTION - I WOULD LIKE YOU TO ANSWER IT. PROPERLY.

it is unnecessary to mix and match

Why is it always so?

DITTO CLARIFICATION, BTW

it just looks so Awful!

Don't be ridiculous. Even though you can't help it.



I wonder if you will answer, or if this is going to be yet one more of your barking mad interjections of utter rubbish.

Ooh - I've got one of those too. Although mine is black. How clever of you to realise that I used it.

 

[ban-all-sheds]

Yup - these would look ghastly next to each other, wouldn't they.

And imagine seeing these adjacent in a CU - you'd lose your lunch, for sure.

Clown.

Dunno. Is it type-tested to EN 60439-3?

Or even BS EN 61439-3 nowadays...

Damn! Living in the past again!

Type Testing is the answer for Ban!
Please don't use Block Capitals all the time - it is considered bad manners.

Type Testing is the answer for Ban!

and you don't think fuse carriers and MCBs manufactured in the same range by the same manufacturer are not type tested? Come on! You cannot believe that to be true

If a correctly installed CU, has a breaking capacity of 16ka, surely breakers alone will comply, if all are the same make, and the Supplier's mains fuse or Switch fuse upstream of the CU is correctly rated for the unit in question (usually 100amps, 80amps or 60amps)??

They will, but there are other reasons for installing fuses instead of MCBs.

 

[stillp]

How about "consumer unit"?

Maybe, if type-tested as an assembly.
Can a fuseboard contain MCBs?

 

[Taylortwocities]

Kai, you must be smoking some crazy stuff!

Browse the Hager product information. It clearly states their CUs can accept fuse carriers, MCBs, RCBOs and RCDs.

Of course fuses are suitable for some circuits. For example, if running a circuit to form a sub main, it is best practice to use a fuse at the origin. Better discrimination.

Or is your problem that Wickes don't stock Wylex fuse carriers?

Consumer Unit is a terrible name, not even vaguely electrical, and patronising to boot. They should be called 'distribution board' or 'electrical board/panel' or 'mains circuit board', or something. Depending on the situation i still use 'fuse-board' often, as everyone knows what you mean, nobody (except electricians and DIY geeks) has a clue what a 'consumer unit' is.
