Part E

Chris Pearson
Yes, that's part E, not L, M, or P! ?


Scenario is studding wall between a landing and a bathroom. I don't suppose that anybody in the bathroom will be perturbed by noises on the landing, but one doesn't necessarily want to hear various splashings.


So we have a 2nd floor ring final coming and going in the wall along with the lighting circuit. 


I may be a bit thick, but I don't find the Part E Approved Document easy to interpret. If any wadding is to be put into the wall, then we potentially end up with Reference Method A, in which case the 2.5 mm2 cable is downgraded to 20 A. At this stage I want to ignore the possibility that two legs of a ring should be derated due to grouping.


My feeling is that the requirements of Part E can be met without recourse to wadding, but what I would like to know is whether any of you have encountered this problem, and if so, how you have addressed it. Many thanks. ?

    I personally don't see the point in insulating internal walls.



     


     


    That is true if you live on your own, or everyone in the house goes to bed at the same time and has quiet hobbies. In a family house this is less likely.

    As an example I am  very pleased to have blockwork internal walls upstairs. This is due to my sons drum kit, and the fact that Mrs MAPJ1 gets up at about 5 in the morning when she is commuting, I have no desire to hear drumming over whatever I may be trying to concentrate on, nor be woken by the sounds of clanking about in the bathroom and so on. As it is, if the windows are open the loudest early morning sound at certain times of year is the sheep in a field about a km away. I'd be disappointed if it was the other occupants.

    It may be that if you live in the shadow of a city as well as having PME mains you develop a tolerance for more background noise.
