Not Permitted use of bs3036?

[diGreez]

Hi,

why bs7671 for PFC may not permit use of bs3036 semi-enclosed for overcurrent protection on the TN-C-S installation where PFC is 1.2kA if bs3036 are rated between 1kA to 4kA? :dizzy2:

Am I missing something?

Thanks.

where in bs7671 does it say that ?

 

[diGreez]

as much as I searched the regs it does not say anything about not permitting, but I have a question on may assignment, so I thought I missed something. and now that question does not make any sense to me... is it just C&G wording on the question just to confuse us...?

Oh, just found it! OSG Appendix B Table B1. :smile5:

And is that the question word for word?...lol...

There’s this weird thinking about homework. Some people believe you should do your own research in order to learn.
Others are down right lazy and expect other people to provide answers.

I'd be happy if they typed in the question, word for word.
Not some half arsed version that you've got to rack your brains trying to decipher. :banghead::banghead::banghead:

diGreez, if some 3036s are rated at 1kA, some are rated at 2kA and some are rated at 4kA but there is no way of telling which is which, what must you assume?

It needs a consumer unit upgrade to these spang dangly RCD's....imp2:
