Fuse Identification

[solavie]

Doing some work on a flat. Moving a light. What fuse type is in the picture. There is no marking on the fuse.

Thanks.

Sorry but I don't see any fuses.

They look like old crabtree mcb's bs3871 i believe, definately not fuses though

Looks a bit light on bonding too

 

[Sintra]

Yea I'd go for 3871 also the markings should be on the side of them.

 

[monkeyelectric]

And its open back mounted on wood and made of wood too

 

[telectrix]

so was kon-tiki, but it crossed the atlantic.

And it's turned on and opened someone could get a SHOCK.

Its also shiney so it could dazzle you and you'll fall off your steps when you open it

Crabtree c50 3871 m3 if I'm not mistaken. One of the worst boards you will ever have the good fortune to work on.look at the live parts on that baby!

Yes it is a nightmare. There was not MET or bonding to gas or water. Aware it is switched on. But I switched it off when taking the l cover off and on (Guess what it is METAL) as there is a great risk of shock from the top of that box. It uses the conduit as the cpc. tested the continuity. The light was in the bathroom, so had to cross bond everything there as well. Lot of work has been done there, new kitchen and bathroom but they forgot to modernise the electric. No Rcd

Meant MCB (not fuse). This is 3871 from your replies.

Avoid Flats

Thanks

They have different kA ratings depending on age of the particular C50 mcb which is identified by the colouring of the writing on the mcb either white or yellow writing. I can't see what colour yours is from pic

Im sure the colour defined what type it was not the kA rating

 

[onions1066]

Which identifies the KA rating they are 3871 type 2 the colouring of the lettering is to identify the KA rating I have the memo from Crabtree technical if you want a copy

im fine i have my own technical info thanks, but ive seen white and yellow crabtree breakers side by side both stamped with 4.5kA, white was type 2, and yellow type 3.
