A question i noticed on the internet, your thoughts

[electro]

Hi I was on internet and noticed this question (its not my question) which seem quite unusual and just wondered what you guys thought of this situation. I notice the reply to the question did not answer the question. I cant see anything wrong......




Subcategory - 1. BS7671


Question
I was doing some work for a client the other week and upon going upstairs, noticed a 45A cooker switch/socket outlet adjacent to the bathroom door. When I enquired as to why it was there, my client said it was the shower switch and a socket for her hairdryer as she didn't have a socket on the landing. Which got me thinking if this was entirely appropriate.


The shower circuit was wired in 10.00mm T&E with 50A MCB and 100A 30mA RCD with the label 'Shower and socket on landing'. The shower is 9.5Kw and the board is 3 / 5 way split load.


Answer
BS 7671:2008 allows a socket outlet within the bathroom to be fitted provided it is 3m from the boundary of zone 1 and must be protected by a 30mA RCD.


A 10mm cable can carry 52Amps (from table 4D2A) if the cable is installed within a building void without insulation. Table 4D5 gives current carrying capacities of cables covered with insulation.

Assuming the switch is on the landing side of the door, cant see a problem.

No different from a socket on the landing really.

I agree with Jason. If it is outwith the bathroom then its outside the remit of special location. If the 3 m rule applied to outside bathroom doors niot a lot of people would have sockets on the landing.

Sounds ok, only thing i would look at is the unit label, is it labeled Cooker next to the isolator swicth? If so it would need labeling correctly etc.

Thanks guys, I thought it was a reasonable question asked to a professional council and as per usual they have not answered the question at all. That's why I like this forum people answer the questions given to them, with real answers not “you might want to look at so and so reg that has nothing to do with it”


Thanks
