Hi Guys just looking for a bit of info. I've recently moved into a new house and want to replace the shower. There is a 10.0mm T+E supplying the CCT. However, upon closer inspection, i noticed that it's supplied solely from a 63a dp rcd, with the supply side fed from the meter and supply side to the shower. is this ok? Im looking to replace old 9.5kW shower with new 10.5kW. Help would be appreciated.

Did you test the circuit for insulation resistance? Earth fault loop impedance? Have you tested that the RCD works (an external test, I mean, not just pressing the button)?tony3210 said:
Blimey thats a bit scary - I wonder why whoever put the shower in didn't put the DP switch in. All there is is the 63A main switch and the 40A M6 type 2 breaker in the shower mini CU enclosure. Mind you this is literally in a cupboard with the other CU right outside the bathroom door - perhaps that the distance between the shower CU and the switch would be less than 30 cm is why they didn't bother.
We are moving the CU stuff anyway and thought the shower cable would either need enlarging to cope with longer run or extending so we can sort out the DP switch then. Gor blimey it never ends ehy? Must be far easier to build a house from scratch.

everyone mentions needing a shower isolator but we have never been shown what the reg in question actually says.
if a shower CU is close to the bathroom anyway then I can't really see any highe need for a seperate switch.
can someone enlighten us on if there is a reg requiring shower switches and if so what it actually says.

Resurrecting this old post as had a debate on the same subject today. In my opinion, a situation where a separate shower CU is installed with say a 63A/30ma RCD as the main switch or indeed an RCBO then this can satisfy the requirements for isolation as well as OPD/fault protection without the need for a separate shower DP switch.
Thoughts ?

On what basis are your opinions more worthy than mine or any others on this forum ?
What have I said that is **** ?
131.14.01 - "Effective means suitabley placed for ready operation shall be placed so that all voltage may be cut off from every installation
from every circuit thereof and from all equipment as may be necessary to prevent or remove danger.
Explain how an RCD in a shower consumer unit does not satisfy this ?
The moot point would be the "effective means suitably placed for ready operation " bit.
Would you consider an isolator situated outside the bathroom and buried under a pile of towel as being "suitably placed"?
