3036 with RCD

[kant]

Can any one tell me if i need to put rcd on 3036 cu if I am just changing socket faces cause i was told i did?

 

[TPES]

im asking due to a PIR on this install.

cant identify the cut out rating and the tails look very small, from the cutout to the meter is 16mm, out the meter to CU looks smaller to me, poss 10mm..

also signs of overloading on lights, (cant see how though, only 5 pendants on the circuit)

and broken fuse carrier
and no cover on the front for the fuses

I can't comment on the tails size from a photo.

The discolouring on the second white fuse carrier looks like 'flash' to me, from where a BS3036 has 'blown' on a fault.

They don't make 'em like that any more (thank god).

If your supply fuse is a BS1361 and your installation is domestic single phase then you can use the s/c capacity of that device (16.5kA).
not that its important for this post but i thought a 1361 was 33Ka

It is 33kA but the BS60439-3 UK annex only allows us to allow 16kA when used for this purpose.

That was my first thought but then noticed the customer had put 15a fuse wire in to replace the 5.

the tails had been doubled back in the terminals which is why i thought they were 10mm. could be one of the old dodgy size conductors.

Is it me or are the L&N of the 6mm T&E terminated into seperate fuses????

1361 type 2 is 33ka 1361 type 1 is 16.5 ka

looking at the pics though the discolouration of the fuse carrier is due to the fuse blowing and not to overload , meter tails look like 16 mm ,and if im not mistaken the fuse carrier is a 3036 rewireable , if i am mistaken and i could be then the fuse may will be a BS88 or a 1361 , think ive mentioned them all , but id be suprised if the fuse was any higher than a 60 amp , have a close look at the fuse carrier it may well give you the fuse rating (capacity) on it

lenny looking at it somethings not right you can see a black identified with blue tape and a neutral on the L/H of the neutral bar , but why has the black been marked with brown tape is it 2 blacks im confused ????? 3 blacks 1 red !!

Sid.....what's occuring there then???

 

[TPES]

It does look odd at first glance.

Looking into it shows the shower circuit is wired via 6.0mm 4 core stranded flex, not sure what the cable BS number is, has a thick grey outer insulation, copper strands.

This is why they are all black but have been taped up to identify conductors.

No markings on the fuse carrier as to what size or type. im guessing BS88 because of its shape/length

 

[nickblake]

now it makes sense , im thinking BS 88 too

 

[TPES]

I know its each to there own, but what codes if any would you give just from what you can see on photos and from what ive said, if doing a PIR.

anyone else confirm 4ka is the rating for 3036 fuses?
if not and its 1ka for the 5a lighting for example does it not matter that my PFC is greater than this cappacity?

Did you not see post 15?
I don't just guess!

Yep seen that, heard you loud and clear..

But i dont think i have a 1361 main fuse..

and i always see this ka rating 1 to 4 on 3036 fuses but which is it... 1,2,3 or 4?
