Replacement shower

[keniff]

If your replacing a shower like for like power wise, are you under any obligation to supply rcd for this? As no alteration has been made to the circuit and no change of opd has been done?

What do the manufacturers installation instructions say? That is what I'd be checking.

Manufactures instructions supersede bs7671 so I would agree. Check instructions.

100% sure that the instructions will state that the shower is to be supplied by a 30ma RCD protective device.

i would be fitting one either way...

The manufacturer's instructions should be taken account of.
However there is no requirement in BS7671 for you to provide RCD protetion when replacing an item of equipment.

No requirement for RCD when changing like for like accessory

If the manufactures instructions state to be rcd protected it does not matter what bs7671 says it must be rcd protected. They supersede bs7671

No they don't.
The manufacturer's instructions are required to be taken account of.
510.3 "Every item of equipment shall be selected and erected so as to allow compliance with the regulations stated in this chapter and the relevant regulations in other parts of BS7671 and shall take account of manufacturers' instructions."

That relates to the process of erection, i.e. how high up the wall, the distance from windows or doors etc.

With regards to manufactures' specifiing the provision of an RCD in their instructions.
As far as I'm aware, most appear to use the word 'should', or in the case of triton, state that the instructions are for guidance.
As far as I'm aware, the only condition that must be met in all cases, is that if installing a 230V shower, it must be connected to a 230V/240V supply.
