Rcd protectio in bathroom

[Murdochcat]

To clarify a little for those who don't know ....

All circuits serving a bathroom or passing through Zones 1 and/or 2 of a bathroom (but not serving the bathroom) have required RCD protection since the 17th edition in 2008.

I’ve always been a bit amused about the line “passing through “ above!

Who in their right mind would do this at all?

I had that job to remedy.
The shower room had been a cupboard, when converted the cables running top to bottom had been placed in a trunking right beside the glass screen.

The light you have requires RCD protection

At the end of the day it’s a rental and you have a duty of care for your tenants

Yes and agree .. I will always do what is neccessry to bring work up to what needs.

Thanks. I understand the bathroom light circuit needs RCD protection, and I am arranging for an RCBO/RCD solution for that.
What I am still confused about is why item 6.2 SELV/PELV has also been coded C2 as a separate item. If the bathroom fan/light is standard 230/240V and there is no 12V SELV/PELV equipment or transformer, would 6.2 normally be marked N/A rather than C2?

It's presumably fairly uncommon but, off the top of my head, I can think of two houses I've known in which cables of circuits not serving the bathroom 'passed through' the bathroom in the under-bath space.

The first house I purchased and reburbished I ran mains and comms cables, gas and waste pipe under the bath but of course it's not a 'Zone' if it requires a tool to access. One of my rental properties had heating pump under the end of the bath and non electric Chaffoteaux boiler above.
How the wetpants left it when the boiler was replaced/repositioned

And subsequent removal

The requirements for circuits in a bathroom to have RCDs protection is separate from whether supplementary bonding is required or not.

All circuits in or passing through a bathroom have required RCD protection since the 17th edition in 2008.

Supplementary bonding can be omitted in certain circumstances, and having RCD protection is one of the requirements for that, but it's not the only one.

In any event, 3 RCBOs for that consumer unit will hardly break the bank.




Being generous, it's a mistake.
Less generous options are available.

Either way it's highly unlikely a domestic bathroom has any SELV, and it certainly won't have PELV.
SELV was usually 12V halogen downlights wired to a massive isolating transformer the size of a biscuit tin. All obsolete and long gone.

Still SELV fans available, though not very common to be fair.

My fan is 240 volt currently in the bathroomim a little confussed by the report.

Is the report saying I need to change the fan from a 240v to a slev to pass ?

No.

 

[diycooper]

No.

Is the report assuming I have SLEV device in my bathroom.?

The report is wrong. How it got to be wrong is something only the wrongun that completed it will know.

Lack of SELV could only be C2 if it was required and it wasn't there.
Bathroom extractors can be SELV but do not have to be.

The only required SELV items in a bathroom would be desperately unlikely situations such as lighting installed directly into the bathtub itself.

THe consumer unit in pic. Could anyone confirm if they know if the rcbo are compatible with consumer unit ?

Thanks

Under the bath AND behind a fixed panel isn’t in the zones IMHO

Good point.

 

[diycooper]

Any help.on if there the correct rcbo fory fuse board amyone.

Thanks
