Help with RCD - 100mA to 30mA

[Deleted member 26818]

The excemption for labled socket-outlets only applies where socket-outlets are used by ordinary persons, and are intended for general use.
Which to be honest is a bit pointless, as the exemption is for socket-outlets that are provided for a particular item of equipment, which would not require RCD protection in any event.

But even as with socket outlets TQ if the installation is deemed under the supervision of a skilled or instructed person, then even if the cable is <50mm and not mechanically protected you do not need the additional protection by RCD

No skilled or instructed person in the office I'm afraid and TQ was correct , the cables are run in the plaster (less than 50mm and not mech protected)

No skilled or instructed persons.
I suggest that you point out to the duty holder, that they are in breach of the statutory requirements and are breaking the law.

Hi SpinLondon,

Sorry, I missed your post above re:EAWR which has cleared up quite a few things....

I went to the length of checking the 'definition' of a skilled person with the NAPIT tech line as well, as I wasn't 100%, hence my post and mis-understanding.

Just for the record, they said that a skilled or instructed person was relative to the electrical installation, e.g. a permanent onsite technician...... so they got that wrong.

What you have said makes sense.......

So (if we take it to the letter), legally an employer has a duty to ensure its has at least one member of staff has the relevant skills training to a operate socket / is aware of the concequences of drilling into walls etc and is therefore classed as skilled...... This individual can then instruct others who haven't had any training yet.... and they are classed as 'under supervision' or 'instructed'- Have I got that right?

And with the EAWR covering every working environment, then the above will remove the need for a 30mA RCD to be present (as far as the regs is concerned).

.........so the only time you are going to see a situation where an 'ordinary person' comes into play is in a domestic environment, as the EAWR is going to enforce all other situations to ensure they have a skilled person?

How am I doing...???

Sounds good so far.
There are circumstance where RCD protection will allways be required, even if the installation is under the supervision of a skilled/instructed person.
For instance where there is a socket-outlet used to supply mobile equipment outdoors, and for circuits of special locations.
Then there are installations such as in hotels, residential care homes, perhaps internet cafes. Anywhere where a member of the public as an ordinary person would have unsupervised use of a socket-outlet.
