The only time a board would not have to comply with the 17th, is if the design was done before the 17th came into force. (As in the case with the Olympic Village at Stratford).I did six board changes in a private club and was told by my assessor that they would need to comply with 17th edition so would require total RCD protection. You cannot use supervised reg as you do not know what people are going to do in nursery. Being done by a NICEIC contractor does not surprise me that he did not comply as said in a previous thread a NICEIC contractor who fitted a board at the beginning of this year used a RCD main switch board on a job that I looked at how does that comply.Batty
There is no requirement for any Distribution Board or Consumer Unit to contain an RCD in BS7671. As such you can conduct a board change, state on the EIC that the work complies with BS7671 and note under Comments on Existing Installation the lack of RCD protection. However, that would not be necessary if the installation was covered by the EAWR.
It does not matter what people are going to do in the nursery.
The regulations allow for RCD protection to be ommited if the installation is under the control of a skilled or instructed person.
By Law an installation must be under the control of a skilled or instructed person, if that installation is in a place considered to be a place of work.
Here is Regulation 16 of the EAWR:
"No person shall be engaged in any work activity where technical knowledge or experience is necessary to prevent danger or, where appropriate, injury, unless he possesses such knowledge or experience, or is under such degree of supervision as may be appropriate having regard to the nature of the work."
