New consumer unit? Hope it's not Wylex, Crabtree or Volex

[Steve]

Testing the MCB in isolation would be the sensible option here. By which I mean leave it connected to the busbar but remove the circuit wire. Connect tester between the MCB and neutral.

Dont they test MCBs at the factory?

 

[seasickstevie]

Of course all variations of RCDs are tested also, but the RCD test in installation is more to do with testing its response with return path to earth in that particular set of circumstances.

It's not just the three brands affected either - Electrium make MCBs for several wholesaler 'own brand' CUs
Steeple for a start: http://www.denmans.co.uk/mcb_recall.html

Then why didn't they state that in their other recall notice??!!

There's another mcb with the same characteristics as the Steeple ones. Anyone remember which 'brand' it is? So they may have the same problem?

EDIT; GE perhaps?

 

[flameport]

The other brands could be Newlec or Sector, as they (and Denmans/Steeple) are all owned by Rexel.

This states whole consumers units need to be re-called, doesn't it?

Having phoned that number they say just the MCBs.

 

[flameport]

The Screwfix notice doesn't say anything about Crabtree - yet Screwfix sell Crabtree MCBs and consumer units with MCBs in them.

Really?
Their re-call programme is useless.

So where they are re-calling consumer units, is this just because of the MCBs that they are pre-loaded with?

Their helpline is hopeless.

I bet there's some red-faced people at Electrium.

Does anyone have one of the affected MCBs?

I'd quite like to get hold of one and carry out some tests on it

 

[maguire]

I raised the question of MCB testing a while back I don't recall on which forum as a result I got a reply about current injection kit it's about the size of a small garden shed

Nonsense!

I've got an MCB tester.

I've just tested a B32 MCB (at 120A )

I wondered how long it'd be till rob got his big welder out again

 

[comms]

Crabtree
Wylex
Volex
Steeple
Sector
Newlec
Alto

If you contact electrium, they give you the option to let them replace the MCBs or you can. They told me that they will pay £ 75.00 per job. It only refers to MCBs not consumer units
