Old fuse removal.

[brs73]

Afternoon all. Does anyone know how to remove this fuse. !!! We’ve pulled it, undone the screws But it’s not budging. , it seems like there’s something mechanical holding it in place ???

 

[telectrix]

try the brass nut at the bottom.

Is that the supply cut-out and still live?

Let’s hope not.

have watched the associated video, and there’s no crackling noise or sparks.... so I assume it’s dead.

Same question, similar fuses, possibly slightly newer, on here.
No resolution.

Where's Tony when we need him. ?

@Lucien Nunes might know, may have one in the museum!

I assume the arrow on the left means lift upwards, maybe a bayonet connection?

Are there screws in the holes top right and bottom left? could be fixing the carrier to the bare,

Like the little 5A slidelok fuses? Only came in black I think.

is there a screw that tightens the grip of the fuse carrier? Perhaps pushes a wedge in so the fuse can’t be inadvertently pulled out.

I suspect it is just tight (by design, and by age) but especially with old stuff you really can't tell what is a sane force to attempt and what will break something. If live, that gets nasty real quick.

Difficult to tell from the video, but the screws inside the ceramic holder don't seem to move with the holder, perhaps they just need undoing.

 

[Lucien Nunes]

If you've undone the clamps it should slide out. It might have welded, doesn't look like you are pulling very hard. But is it live? I don't think we can tell from the video.

DNO fuse puller...for those tight ones.

What a great tool! Proper grip and hands that bit further away should the worst happen.

Still a job to be kitted up with face shield, heat/flame resistant overalls, and arc-flash rated gloves though (assuming it is live).

Undo the screws in the fuse holder, they are wedge fuses, looks like a metal clad cut out, which should not be worked on live. You should NOT be messing with it, naughty naughty!
