Official Stance from Elecsa on RCD for socket outlets!! from Luke @ Elecsa Tech Support

Code 2 and Code 4 are Both Correct coding for the installation, however the Electrician has to make his own judgement on if its unsafe or just not up to date..!!

if you were using equiptment outdoors whats to stop the customer using a RCD plug in device !!???

he did go on to say that code 4 for would be the automatic choice in most situations unless deemed otherwise ONLY by the ONSITE electrician.

what about coding a crabtree c50 db with bs 3871s inside? would you code 1 it because of the exposed busbar?

coding a crabtree c50 db with bs 3871s inside?

i would not code it as you have to remove the cover to get at the busbars!! just the same if a spark left the bus shield of a domestic CU

 

[jparker3007]

exactly my point but were being told to code em and change em

 

[DurhamSparky]

oh well bit of extra work!!

 

[jparker3007]

[DurhamSparky]

I attribute code 2 to absence of RCD protection to socket outlets that may supply equipment outdoors as this was a requirement of the 16th ed also. For other instances a code 4 i.e, cables in walls etc.

BS 3871 might not be recognised in BS 7671-17th ,But so are other things. BS 7671 is mainly concerned with the Domestic side of things.There are still a lot of BS 3871 around, mainly in commercial/industrial installations(we test a lot of em),there's absolutely no reason to code them as!

The difference between the 16th and the 17th regarding socket-outlets for use outside, is that in the 16th, it was anythat may reasonably be expected to be used, whereas with the 17 it's any that are used.
