Quick question, instead of replacing like-for-like, I'd like to upgrade
a 7.5kW shower to 9.5kW, obviously got to change the cable from 6mm to
10mm so this then becomes a "new" install.

Depending on the length, and how the cable is routed, there are
circumstances where the 6mm^2 cable will still be adequate. It will
depend on the details, but the current carrying capacity of 6mm^2 can be
as much as 47A (and your load is 41A)

Not because its a shower as such[1], although fitting one for a shower
is very common. However if the cable run is "unprotected" (i.e. cables
not enclosed in an earthed metal screen, and its buried in a wall at a
depth of less than 50mm), then it would need an RCD to comply with the
requirements for cable protection.

[1] Although main and supplementary equipotential bonding will need to
be present and to an adequate standard, and you will need to verify the
circuit design by calculation.

The run of 6mm is roughly 10m, just seems a bit too near its limit for

Main reason for asking was that it's currently protected by a fuse
rather than MCB and I was a little concerned by the possible disconnect
time in case of a fault. Have to check the cable route before going further.
If a wanted to add an RCBO in an enclosure, is there a way it is
permissible to do it from the existing fuseway in the CU or does it
*have* to be done as an additional CU with Henley blocks? If the latter,
I think I'd prefer to get someone else to do it and sign it off.

Lee

Ok, so having read through the links I can fit an enclosed RCBO via an
existing fuseway and on balance this seems an eminently sensible thing
to do.
Now, assuming the routing of the cable is ok and the thermal rating is
not exceeded, does using an RCBO mean that 6mm cable would have a
sufficient disconnect time?
I still think I'd be happier uprating the cable to 10mm though

If hanging off an existing fuse, then there is no need for a RCBO (i.e.
combined RCD and fuse in effect), and an additional RCD would be enough.

not exceeded, does using an RCBO mean that 6mm cable would have a
sufficient disconnect time?

An RCD will limit the disconnect time in the event of an earth fault.
However is preferable to design where you can such that it would comply
even without it. You sometimes also need to consider the disconnect time
in the case of a L to N fault, but generally, if its ok on L to E faults
then it will be ok on that as well.

I still think I'd be happier uprating the cable to 10mm though

If you can furnish some details, we can work through the checks and see...

To start with we need to know:

Details of how the cable is routed - i.e. in a chase plastered into a
wall etc?

The total length of cable.

What type of fuse is there currently - rewireable or cartridge fuse?

And if you know it, your earth loop impedance (if your metre has been
changed in the last few years this may be written onto a label near or
on it - it would say something like "ELI: 0.3 ohms"). If you don't know
that, then what type of earthing[1] arrangement have you got? (so we can
assume the nominal worst case values).

[1] You can use the details and pictures here to work out which:

(chances are its likely to be TN-S or TN-C-S unless you are out in the
sticks a bit)

I believe that is wrong now.

If you replace the cable with a larger one then the work you have done
has to comply with the current regulations which require an rcd for
every circuit in a room with a bath or shower.

Regs 510.2 and 134.1.1 apply and I have never seen a shower installation

Can you say why you think that and give an authority. All new work has
to comply with *current* regulations. I cannot see how this long after
the introduction of the 17th edition you can elect to use the 16th (or
15th, 14th, 13th etc) edition.

However I would agree with you if you were just changing the shower
unit, but not if you are doing any work on the circuit.

Yes, sorry I was not clear. The cable protection issue would only apply
if also changing the cable or installing a new circuit. If just changing
the shower, on the same cable (assuming the circuit as a whole is
adequate) then you would not necessarily need to add the RCD for that
reason. Note however that many shower manufacturers instructions will
mandate the use of a RCD anyway.

I would have to agree with that - my interpretation would be that an uprated
cable/circuit would consitute a new circuit - meaning the current regs
apply.

In any case, RCD protection for bathroom circuits is an eminently sensible
idea - and there are ways to do this even if the CU cannot conveniently take
an RCBO for that "way" - eg add a 30mA RCD in a little box after the CU at a
convenient location.

I have not followed the whole thread - but is the OP uprating the protective
device (fuse/MCB) to a higher current? If so, that is no longer replacing
like with like.

I may well be mistaken here. I thought that if the OP only replaces
the shower, then its not a new circuit, only a new appliance, and thus
doesn't need 'up'grading to the 17th edition requirements.

Maybe I'm overly cautious, but I would insist on an RCD or RCBO for an

I am being pedantic about the regs here rather than saying what might

then that part of the circuit you modify has to be brought up to 17th

circuits). There is no exception to the reg requiring an rcd on a

If you are modifying the circuit (i.e. uprating cable or protective
device) then yup agreed. However I believe that straight swap of just
the shower unit onto an installation that complied with the 16th edition
requirements (but did not include a RCD) would also be acceptable
(assuming the fitting instructions don't mandate a RCD).

Having said that, for a shower, I would fit a RCD as a matter of course
if it did not have one.

Just to update, I was obviously having brain fade because I totally
failed to notice the RCD that was already sitting there.

Since the existing 6mm was clipped to surface for it's entire 10m length
(runs up the dividing wall then straight in behind the shower unit) and
was already protected by a 40A fuse and 45A DP switch I just thought it
was easier put a 8.5Kw unit in as a "like for like" replacement.

It's more or defacto mandatory for any circuit, unless you can bury it
50mm below the surface or mechanically protect it, or surface run it.

It will also be necessary if you have no supplementary binding in the
bathroom under the 17th.

Oh dear!
45 years ago in my first house I fitted and plumbed in a Triton 7KW electric
shower over the bath. The cable went straight down the pipe box and finished
up in the meter cupboard. I was very nervous when I connected the cable to
the electric meter. Nervous is better than saying that I was **** scared.
The meter had fuses. No RCD stuff.
There was no isolation switch for the shower.
I was dead proud of my shower.
I wish that I was 45 years younger.

It's more or defacto mandatory for any circuit, unless you can bury it
50mm below the surface or mechanically protect it, or surface run it.

It will also be necessary if you have no supplementary binding in the
bathroom under the 17th.

Oh dear!
45 years ago in my first house I fitted and plumbed in a Triton 7KW electric
shower over the bath. The cable went straight down the pipe box and finished
up in the meter cupboard. I was very nervous when I connected the cable to
the electric meter. Nervous is better than saying that I was **** scared.
The meter had fuses. No RCD stuff.
There was no isolation switch for the shower.
I was dead proud of my shower.
I wish that I was 45 years younger.

Funny how you didn't die. RC whatevers are for pussies.

Showers don't use enough to bother doing that. You obviously connect something which uses more juice that side.
