Replacement fuse

[bolst3r]

Seems like one in my consumer unit is on the way out, it's a slightly older type and i'm struggling to find a like-for-like replacement. Is there a newer model that will likely be compatible?

Current one: MK LN 5932s B32

Sorry, that would help. No.4 is not tripping properly and is arching at times. I've had one go on a newer consumer unit where it burnt out the back but never tripped, was fine once it was replaced. This one is quite a few years old, probably not square on the bar doesn't help.

MK said a 5932s will fit, I must be losing it as can't find one.

Thanks Andy, saw that but as it is used I wasn't sure if I would end up being left in the same situation.

Called MK technical and they said whilst the LN5932s isn't available the newer 5932s is and that's compatible even though the switch button is in a different location. It's an older consumer unit so at some point it's probably worth replacing. I have an extension planned for later in the year so that's a perfect opportunity. I just need something to get me through.

ok, chaps. Seems like ebay is probably the quickest/easiest. Ordered – thanks for your help.

... No.4 is not tripping properly and is arching at times...

What do you mean by "not tripping properly"? What are you doing which should make it trip?

Kind Regards, John

nothing really but i've noticed a couple of times recently the sockets in one room have lost power but the fuse hasn't tripped, when I flick the fuse on/off it seems fine. Last night I heard it arching and a lamp was flashing on/off, again it was fine when flicked on/off.

I had the same with another fuse in a new consumer unit. The power to the fridge went but the fuse never tripped, flicking it on/off it was fine. I wasn't happy with that so checked it to find the back of the fuse had burnt out. There were a faulty batch of MK fuses a few years back causing the issue.

I'll replace the fuse and go from there.

Fair enough. It therefore definitely does sound as if it is a faulty one ('breaker'/MCB, not "fuse"!) - which, as you have surmised, needs to be replaced.

Kind Regards, John

It was a faulty MCB, the old one had some marks where it had been arching. Back together and been fine for several weeks now
