Outside socket, 30m/A RCD exception??

[normanton]

Hi guys, bit of a strange one (long story). But do you know of any exceptions or any loopholes where you don't have to provide an outside socket with 30m/A RCD protection. (these sockets im talking about already have 100m/A protection anyway)

Is there an issue with what they are supplying causing nuisance tripping due to design leakage, what kind off sockets are they (3ph, 1ph etc 400v,230v) or are we just talking standard 13amp s/o .... what are likely to be plugged into these sockets?

I don't think so, they've got it covered from pretty much every angle!

If it's under the supervison of a skilled person (i.e. you), then it could be as you pertain to. But the previous sentence implies ONLY you have access / control over the said socket.

For example you may wish to install a socket at home that has no RCD protection, but then has a "plug in" RCD that you use to check the calibration of your meter with every month. Obviously this would be marked as for "TESTING ONLY" in indelible ink, and a comment on the certificate as such.

I think there may be other reasons but I'm no expert.

Possibly using a locked cover may get you away with it, but as darkwood asked what is the SP?

Are you saying can you add an outside socket with only 100mA RCD protection?

It's a 4amp test socket which is part of the DB. It has a flap on it and it's single phase 2 pin, supplied from a 4amp mcb. It has a 100m/a main RCD feeding it but if these test sockets need 30m/a protection it means I'm going to have to either install a 30m/a rcbo or change the main RCD to 30m/a. And I don't fancy doing that on price!

What do you mean by 2pin... is their an earth as in the casing of the 2pin plug been metallic and earthing onto the socket, what are they testing? what is been plugged in?

All general purpose socket outlets require 30mA RCD protection, and it does not matter whether they are inside our out. There are other considerations which will decide if you RCD the cables, or just fit RCD outlets.

Does the socket comply to the regs as 2 pin ?

OP has already informed us they are 2 pin sockets for testing purposes so not general use hence im looking for further info, but deffo nothing wrong in what you say.
