RCD socket outlet.

Former Community Member
Former Community Member
Hi all,
Any comments on this one most welcome!
A customer wants me to replace an existing one gang 13 amp socket outlet with a double.
The problem is that there's no rcd protection there, so i'm thinking that as I am in effect adding a socket outlet I should fit an rcd protected one?
If I were replacing like for like it wouldn't bother me at all but the fact it's going to be a double makes me think an rcd protected one is the thing to do, just seems a bit ott to fit one rcd protected socket when there are probably 20 others that aren't rcd'd!

    Wrong about the fault current rating by a long way.




    BS 7288:2016 5.4.8: Standard values of the rated conditional short-circuit current (Inc) The standard values of the rated conditional short-circuit current Inc are as follows: 1 500 A – 3 000 A.

    Different power factors apply for each value. So yes, the two types of RCD are not to exactly the same spec, but it would be an odd installation where a 13 A SRCD was vulnerable to a higher PFC.
