Wylex 6A plugin MCB

[Abacus614]

Evening all. My neighbour just got me out the shower as he has no lighting. He's got an old wylex consumer unit with retro fit MCB, the one with the red button to trip.

Anyway after removing the cover found nothing between L-N and L-CPC out going on both lighting circuits, but power on the busbar. Now I'd have to conclude both mcbs were knackered, but any ideas why both would go at the same time?

Could a voltage surge fry one of these older type MCBS?
Does it smell of burning at all?

Don’t suppose there’s another 5A one you can swap in until you are asked to upgrade the board

 

[buzzlightyear]

Did you take out the mcb out to find no LN/E not there.

 

[SparkyChick]

Is it possible they are linked elsewhere and one of the breakers gave up the ghost a while ago, the other just has and thus revealed the link?

They sometimes don’t reset, take then out and bang them on a flat surface (very technical)

 

[buzzlightyear]

Some times you need to keep pushing them and till engaged.

No unfortunately not. They asked me to upgrade the consumer unit, which I'll do for them as and when but for the time being they are going to pick up a replacement 6A from good old screwfix. Just seems strange both have gone up the shoot.

Done that but they don't push in with any conviction. They seem to have no resistance behind them, if you get what I mean.

You must have a old 3036 in your den to tie them over.

Haha my den isn't that old.

A tent then.

Any testing carried out? apart from concluding that both MCBs are duff? just asking.

No mate too dark, I just got out the shower......

Screwfix and cef do sell them . But as others have said best check the circuit It could be one circuit on 2 mcbs

Thanks Flanders.
