Funny how the onsite guide makes reference to a fuse (dno) that we can't actually open up and look at...

Ridiculous isn't it? You potentially can't complete an EIC or EICR without knowledge of the DNO cutout fuse type/rating, but legally you can't pull it to see.

I know this has been asked before but I can't locate a thread with a conclusive satisfactory answer...

Got an old Memera 3 board (says it's to BS5486 Pt.13) with a mix of BS1361 cartridge and BS3036 rewireables. PFC is 2.03kA. Breaking capacity of BS3036 may be 1/2/4kA depending on type (S1A/S2A/S4A), but I can't get any clarity on what the type means or how to tell what ones are present here so I have to assume 1kA. Upstream DNO fuse is stated as BS1361 60A type 2 which has 33kA breaking capacity (which I have no desire to rely upon).

So unless someone can tell me a way to honestly declare these BS3036s are S4As, I have an issue with breaking capacity < max PFC. However, I have a recollection of reading something somewhere which says that the breaking capacity can be that conveyed by the overall board enclosure rating, so does the board being BS5486 Pt.13 help me here? Can't locate it in BS7671 (and not sure it was in there anyway).

Advice much appreciated.

Here's a link to a pdf by the IET supposedly relating to semi enclosed fuses / BS 3036...

About as clear as mud when it comes to identifying the different duty cattogaries S1A to S4A
