Service cut out Fuse the red ones.

[Retroviper]

Hi just wondering if anyone knows the rating of the red service head fuses?
I havent come across one with a label on it yet and when I pulled one the other day I was going to have a look but they seem to have something like a rivet holding it together where the screw normally is.
I'm thinking they are all 100 amp but not sure , and what do you do if you need to replace the fuse?
I know that is down to the electric board to sort out but I have blown one before and replaced it

It is a solid link, not a fuse

Ok so what protection is there pre-main switch on the cu?

 

[lamb]

A fuse at the origin of the supply, normally a ryefield board or similar in the basement or other intake position for all the flats

Just to agree with Lamb, usually find the 'proper' fuse hiding in the basement or distribution cupboard.

I was also baffled by this the first time I saw it!
