If the cable is OK then i'll probably just swap the showers then.
Really don't have the money to get an electrician to fit an RCD and the associated work. Hard times at the moment!
If it really was required I'd have to look to repair the old shower instead.
Thanks everyone
(Just hoping the cable isn't any smaller now!)
4mm² would be adequate in this situation as long as it runs through no thermal insulation nor conduit.30 years ago it was fairly common to see showers wired in only 4.0 mm2, so it does need checking.
But that's the point, they don't.If the instructions state the new shower must be protected by an RCD, I can't see how you can ignore that.
Neither would I but he already has one.I would never recommend anyone fitting a shower without an RCD anyway.
But that's not what it says.By a 45 amp isolating switch, though not actually written as such, I think we all know they mean 45 amp MINIMUM.
I find it all a bit confusing. It's not totally clear to me as to whether these 'notes for guidance only' are just an attempt to summarise (as you say, not strictly correctly) the requirements of BS7671 and/or something which has to be treated as "MIs" (SHMBO - at least until next year). I presume you are assuming the former?The instructions state:
5.1 A 30mA residual current device (RCD) must be installed in all UK electric and pumped shower circuits. This is not strictly true.
It is true for new installations but ...
We've discussed that before, and it's a bit ambiguous. It's not clear (at least, to me) whether they are talking about 'parts of a circuit which themselves (the parts) are within a special location' OR 'any part of a circuit which serves a special location, even if the work involves a part of the circuit outside of the special location'. I find it hard to believe that the latter is the intention since, if that were the case, then, say, modification/extension of bedroom lighting would presumably be notifiable if the same lighting circuit supplied a bathroom.The Building Regulations state that work must be notified if: (6A) ... the work consists of— (c) any addition or alteration to existing circuits in a special location. Therefore if an RCD were to be fitted it is notifiable but a replacement is not.
See above - I personally find it hard to believe that the intent is that this would be notifiable if the switch were installed outside of the special location.The instructions also state that:
6 A 45 amp double pole isolating switch with a minimum contact gap of 3 mm in both poles must be incorporated in the circuit.
So, are you saying that if the OP should happen to have a 50A switch then this must be replaced? Would this also require notification?
As above, it depends upon whether one regards the material quoted above as "MIs". If one does then, at least until next year, one is theoretically stuck with anything the MIs say, regardless of whether or not they have got anything to do with the workings of the shower. Of course, what will worry people, even next year is ....Whilst an RCD may be desirable and advisable it has nothing to do with the workings of the shower and therefore the instructions must relate to the circuit.
Even for you and I, it would probably be at the least a hassle to try to argue with them that a breakdown had not resulted from the absence of an RCD or the fact that there was a 45A, rather than 40A, MCB - and I imagine that the average Joe Public would not even attempt to argue the point if a warranty claim was refused for such a reason.Triton Standard Guarantee said:What is not covered: 1. Breakdown due to: ... d) failure to install in accordance with this installation guide.
See what I've just written to EFLI. It is not clear as to whether what is written in that document constitutes 'instructions' or whether (which is what it seems to say) it is a clumsy and inaccurate attempt to summarise the requirements of BS7671. Indeed, what is stated clearly is that the whole section (including the bit about RCD protection) is 'for guidance only' - so I don't think it can really be regarded as an 'instruction'.Ok, so the instructions state the circuit must be protected by an RCD. So you'd have to make sure the circuit IS protected by an RCD, wouldn't you?
How "crappy" is the old crappy one. ? If really crappy and repaired in a less than perfect way then that is even more reason to have an RCD fitted.Thanks guys, I'll check the cable then decide
Just don't have the money for an electrician to come out for an RCD, so maybe I'll just repair the old crappy one
