Bathroom fixtures on fused spurs

[sidekick]

Can't you put an RCBO at the board? As all those spurs would need protection.

Yep. Think I've decided to do that as the little extra cost then covers the whole circuit anyway but as you say in particular the new work in the bathroom. Will have unswitched fuse outlet by t/rail in bathroom and on landing will have bath switched FCU with light switch above and then Floor switched FCU with floor control above so pretty tidy and all safe. Thanks ALL

Totally off topic, but i installed my first socket in a bathroom today!!

:hurray:

How big was the bathroom?

Only the work YOU carry out has to comply with current regs so RCD FCU would be fine.

There is no requirement to bring wiring installed to an earlier edition of the regs up to current standards.

Bonding etc. should be checked of course. :smiley2:

That is correct the work you carry out should comply with the current Regulations.
The current Regulations require all circuits of a location containing a bath or shower to be RCD protected.
Extending an existing circuit, and only protecting the extended part, would not meet the requirements of the current Regulations.

I understand and personally agree with your view,however,that view is not shared by the Esc, as you will be aware,or at least my reading of their advise suggests it is so

Just to make others aware,I have copied and pasted the guidance from them in the link below

This answer suggests only the extended
Q2
When an electrical appliance such as a boiler or electric towel rail is to be installed in a bathroom where there is no supplementary bonding, and the consumer unit has rewireable fuses and no RCD protection, how can the installer comply with the 17th Edition?

If an existing circuit of a location containing a bath or shower is extended, at least the extended part of the existing circuit must be provided with RCD protection.

this one can be seen as the whole circuit and not just the extended part

• Q3. A socket-outlet is to be added to an existing circuit. The work is not being carried out in a special location and the existing circuit has no RCD protection. The new socket-outlet is to be flush mounted 150 mm horizontally from an existing socket-outlet, and connected with wiring concealed in the wall. What is reasonably expected for the installer to do to comply with the 17th Edition?
• A socket-outlet that is added to an existing circuit will need to have RCD protection (except for a socket-outlet designated for a particular item of equipment, such as a freezer).
  In addition, if the wiring that is used to extend the existing circuit is concealed in the wall, then at least the extended part of the existing circuit will need to be suitably protected (by RCD or other means).
• 
  In the end it doesn't seem the sensible action to just Rcd protect a bit of a circuit

That's the problem with the NICEIC, which owns the ESC, they think that they make the Regulations.
In the ESC best practice guide, despite the fact that BS7671 requires all circuits of locations containing baths or showeres to have RCD protection.
There is no recommendation for a code where RCD protection is not provided.

Any work that is carried out, must meet the requirements of BS7671.
BS7671 requires that some socket-outlets and some cables concealed in walls should have RCD protection.
As such RCD protection must be provided (where required) only on the extended part of an existing circuit.
However BS7671 requires that all circuits of locations containing baths or showers be RCD protected.
According to Appendix 15, circuits start (and in the case of RFCs finish) at a DB.
As such the only way to comply with BS7671 when extending an existing circuit of a location containg a bath or shower, is to provide RCD protection for the circuit at the DB.

I would suggest that makes more sense than the Esc
