I think we can always play around with words General to suit our arguments. I suppose we could say that you could have a push light switch on the wall of the bathroom as the actual electrics will be in the wall, not in the bathroom.

I think sometimes you have to just think about what is the right way to do it.... A bathroom is full of steam, we are soaking wet... we need an RCD.

Not disagreeing! I did put an RCD, but I was just reflecting about it afterwards and wanted to sound it out for some other opinions.
thanks for all comments and advice!
 
hi guys 1st post, judging by the fact theres old wylex fuses & old voltage trip then id imagine theres no main equipotential bonding. if theres no main equipotntial bonding then there would need to be supplementary bonding connecting circuit cpcs of the location to any exposed extraneous conductive parts. this is what we have to do on a regular basis. reg 701.415.2
 
I think that the fact that the Regulation states: 'circuits of the location', that it is pretty clear that the Regulation refers to the circuits of the location.
It may even be argued that circuits which pass through the location are also covered by this Regulation, as they used to be in the 16th edition.
I would have thought that it is fairly clear that the zones do not define the location, as there is a Regulation relating to the placement of socket-outlets outside of the zones.

Good answer, one I could not gather myself to post.

Where did you spring back from?:leaving::smiley2:
 
I thought that one of the changes in the upcoming amendment was to ensure RCD protection on any circuit that passes in or through a bathroom to make sure that lights were now RCD protected, which implies that previously they didn't have to be. (Note: I always RCD protect them, I'm just raising a point, don't lynch me)
 
I think Doomed that the original intent was for such circuits to be protected, but it has been misinterpreted. The amendment would be there to redress the misinterpretation.

I heard this too. Would this mean, for example, if you were to carry out work in a premises where the board was located under a bathroom and circuits (not being related to works carried out) passed through this location, that RCD protection would have to be provided for non-works related circuits also?
 
I would say the special location is the whole bathroom. The different zones indicate the ip rated equipment that can be used in a particular zone. Whole bathroom I.e. Special location, all circuits need RCD protection. That's how I determine it
 
Beat me to it
but when you lot go independent and we build a big trench right through the Watford gap then it will be to late to rape and pillage in England Archie
 
here is one. the DB has a rcd covering all circuits but the lighting circuits. the bathroom is classed as a special zone so the lighting in the bathroom needs to be rcd protected "lighting in zone 2,3". what are your thoughts on putting an rcd spur outside the bathroom next to the fan isolator for example?

I think it will look quite pretty next to the fan isolator. Are you connecting anything into it ? If so, what are your thoughts on this with reference to compliance with the regulations ?
 
i did this with ip65 downlights in a home that did not have any rcd's "old re-wireables " i did a post a while back on here. tbh i hope one day rcbo's become really cheap so we could just have every circuit on its own. saves half or all circuits going off at one time XD

reading threw a document from a site it says

Zone 0 is inside the bath or shower itself. Any fitting used in this zone must be low voltage, (max 12v) and be rated at least IP67 which is total immersion proof.
Zone 1 is the area above the bath to a height of 2.25m from the floor. In this zone a
minimum rating of IP44 is required. If the fitting is 240v a 30ma residual current device
(RCD) must also be used to protect the circuit in this zone.
Zone 2 is an area stretching 0.6m outside the perimeter of the bath and to a height of
2.25m from the floor. In this zone an IP rating of at least IP44 is required. In addition it
is good practice to consider the area around a wash basin, within a 60cm radius of any
tap to be
considered as zone 2.
Zone 3 is anywhere outside zones 0,1 and 2 (subject to specific limits) and where no
water jet is likely to be used. No IP rating is required. In addition to the above, if there is
a likelihood of water jets being used for cleaning purpose in zones 1,2 and 3 a fitting
rated a minimum IP65 must be used
