I have just bought these breakers because I couldnt find a wired replacement for a broken plug-in fuse. much cheaper than BnQ and free next day delivery if you spend over £50, £5 otherwise. Replaced all the old fuses and now if something goes wrong its just a switch rather than a fiddley wire. available in 6 amp and up!

p.s. this model is for wylex consumer units

hi,
how does this work with different amp fuses,
e.g i have a
5AMP (lights)
10AMP(cant remember but maybe plugs)
15AMP (shower i think)

are you saying i can replace all of these different ratings with the same new fuse?
or do i need to get different ratings?

No, op isnt saying anything of the sort, the fuse op linked is rated at 16AMP, so for lights,, you need the 5AMP version..

Op is refering to those old fuses where you used a fuse wire.

I would think you'd need different rated trip switches....which they have listed: http://www.screwfix.com/cats/A331832/Electrical-Supplies/Consumer-Units/Wylex-MCBs-Incomers

These are massively over sensitive. You'll spend all you time under the stairs resetting them.

What, these particular units or mcb's generally?

Never so much as reset one once in 12+ years here - Wylex consumer unit, as these are designed for.

Must be just our street then.

These are not particularly cheap, they are widely available -
First place I clicked on was this:

http://www.milliesoft.co.uk/index.php?option=com_content&view=article&id=9:iplayer-mce&catid=1:software&Itemid=11
8.16 each inc. VAT
Delivery is 6 quid.

I dare-say a bit of hunting might find them either cheaper, or perhaps even locally available, as they are such a common bit of gear

Got some in B&Q a few years back. Rarely trip - mostly only when a halogen bulb blows, which seems quite frequent (about every quarter). And much more convenient than replacing fuse wire.

I would be worried if your installation keeps tripping out without an obvious reason, and a test by a qualified electrician might not be a bad idea.

MCBs are more sensitive than even cartridge fuses, but shouldn't trip any more than fuses do in practice.

ELCBs can be a bit more "trippy," but again that's usually due to a genuine fault - you usually get the message which one when you turn on that particular appliance though!

I got these identical items brand new a while ago from eBay for £3 each, shop around I reckon that you will find them cheaper than this.

You can get plenty of the normal circuit breakers much cheaper but these ones look like direct replacements using you old consumer unit.It might be better to replace your box with a new type of box and fit new breakers that you can get from someone like ToolStation.com for £2.99 each The consumer boxes are about £20.

to replace the box it will cost £20 + electrician labour which is not cheap?

I replaced 5amp with 6
15 with 16
and 30 with 32

Will those Ge minitrips definitely fit a Wylex consumer unit? (they do look the same) I've got a very old Wylex consumer unit with a mix of MCBs and cartridge fuses that I installed in my shed and I think I paid more than that the last time I needed a couple of 20Amp cartridge fuses in a hurry. My industrial table saw and jointer both tend to blow fuses occasionally because of their high start up current, so I've been meaning to replace them with MCBs.

Incidentally, the MCBs stick out further than the cartridge fuse carriers, so purchasers may find the cover to access the fuses can't be refitted once the MCBs are plugged in (well mine doesn't fit over them anyway).

Just got a 8 way consumer unit with RCD on the inlet for my shed, loaded with 2x6a, 3x16a and 3x32a, cost £25 delivered from the bay.

The whole point of these compatible units being available is to save on time labour and effort.
They take seconds each to fit.

..... and it's a lot of work to fit on an existing installation, replacing the entire consumer unit.

Thanks for the link anyway - I had no idea I was so near a branch!
