is it up to the customer what protective device is in his installation?

But you can only omit the rcd if it's a like for like swap. If it's not the same rating then it's not like for like.

Which regulation will you be using to support that statement?

Part p of the building regulations.

In relation to an addition or alteration to existing electrical installations.

this thread goes to the heart of the tension between professionals and the domestic consumer which get faced everyday. Part P does, however, still direct us to designing and installing in accordance with BS7671.

Then we we get the bit which says the building should be no more unsatisfactory .... then when the building work was started.

Then we are directed to do any new work according to BS 7671 and we must check the existing installation a) rating and condition for new loads (does not say anything about like for like loads) b) Adequate protective measures are used c) Earthing etc satisfactory.

Then we are given the list of notifiable work, shower room for instance. This bit is important to this discussion, I suggest, as minor additions and alterations are notifiable in this case.

A simple swap, like for like model and rating of shower unit, would ordinarily pass the no more unsatisfactory test, as long as b and c above being satisfied.

Which leads us to BS 7671, if you agree with me so far. Where I suggest if we touch this particular circuit we adopt wiring regs and add an RCD. 701.411.3.6. Uses the word shall, not maybe, might, is optional etc.

cheers

As far as I am aware, there is no requirement to notify when replacing equipment, irrespective of whether the equipment is in a special location.

As for the OP's query, it is up to the person conducting the work to comply with the requirements of BS7671.
In this particular instance there is no requirement to provide RCD protection, as the work is replacing equipment.

But in this instance the equipment been installed comes with a manual and it will say in there that an RCD MUST be installed. No getting around it.

And consider the manufacturers installation instructions, which will advise RCD installation. We can always live in past, and install equipment connected to bare wires circa Edwardian times. But safety moves on.

And rightly so!

It is quite possible that the manufacturer's instructions do specify RCD protection be provided.
Unfortunately, without knowledge of either the manufacturer or their instructions, I am unwilling to offer an opinion as to what such instructions do or do not require.
