height for sockets

[mcfcdwa]

hi there i need to know if there is a regulation height for a double socket in a building re-furb and if there is a max distance to run a 32 amp ring main for them, thanks all

Depends on how extensive the refurb is.

and if there is a max distance to run a 32 amp ring main for them The rule of thumb for a RFC is is to serve no more than an area of 100M squared.

thanks all

If your carrying out this work and don't know the answers to these questions, this is worrying to me

Maybe a quick read of the BGB or the OSG would help.

Yep...agreed....

 

[PC Electrics]

Q2: the RFC should contain no more than 107m of cable (see std ccts in OSG) and serve a max 100m^2 floor area.

I'll buy into that.

Another thing to add, I learn about the heights of accessories before I even started my apprenticeship. My first employer told me that whilst he was looking over my shoulder during my trail period with him. Arghhhhh!

 

[PC Electrics]

And another thing, it's not a 'ring main' but a 'ring final circuit'.

Anyone know how / where the term 'ring main' originated?

 

[fuzzydunlop]

I despair

So then, sockets, MINIMUM height, 400mm or 450mm???? Depends on which book you read!

Yes, it originated in the plumbing industry.......................no not really...................could it be cos it forms a "ring"?????

New builds: Sockets: 450mm to bottom, Switches: 1200mm to top

Existing installation, including rewire to existing properties can be installed at the same heights as the originals providing it in such a way doesn't cause any damage to flex/plug tops...... e.g Socket fitted flat to the floor

I was recently asked to quote on a rewire, the original wiring had sockets at various heights, now the above wouldnt apply surely in this instance, as how could you walk away from a job that you've just rewired, that has sockets in the same room with varrying heights, i mean one at 250mm then one at 400mm den another at 200mm surely in situaions as such we should all be bringing the new sockets to a standard height of 450mm or would that be asking for too much.

Technically doesn't matter, it's like for like

If thats what the client wants (within the price) thats what they get. If they want to pay more (possible extra chasing etc) for it to be a unified height throughout the rooms, they get that

I see what you mean. Well, you CAN do if you want but you are not required to. We can't dictate. Only as stated no worst that existing and not if plug or flex would damage under use.

 

[DaveyD]

Beat me to it fuzz ... and for once I agree.

 

[Mad Spark]

I disagree with that aspect, firstly not only does it not look too pleasing asthetically but it defys the whole idea of the requirements of access for disabled individuals, so as we are all competant people we surely need to make this a point when doing rewires.

I would agree that if we are only changing, or adding to rfc then we can play with the heights but as its a complete rewire i would think that it would require adjusting accordingly.

 

[DaveyD]

But have you seriously met any customer who says "ooooh, yes; move the sockets up and the switches down please - I think they will look a bit odd but I want to enter the part M spirit of things".

A friend of mine had problems on a RFC, spur off spur etc No FCU's. "But the last electrician moved all our sockets up in the sitting room so we are now legal" I kid you not.

Doesn't matter read the regs

As for aesthetically pleasing thats the customers problem not yours. Its all in the quote you give them if you allow for bashing/cutting in new sockets/switches/patching up in your quote thats what they get. If you don't they get to existing

The point being made here though Mad is that if its a rewire of an EXISTING installation then you dont have to site accessories in the 450-1200 band.....but as for aesthetics....then yes it would be better to have all fronts at the same height....when my boss n i undertake a rewire we site accessories within the 450-1200 band...but you dont have to as far as compliance is concerned......another thing is when survaying the job is to see if the client/s are elderly or disabled and you can suggest this to em as i would suspect that most people not electrically minded will be unaware of this.........

 

[Mad Spark]

Its not what the customer say or doesnt say, its up to us as designers of the installtion to have pride in our work and to do that little bit extra to make sure you are happy at the end of each night.
I have read the regulations cover to cover on a number of occasions and yes it doesnt say that in the bgb and the brb but the poiint still stands that asthetically how could u walk away if on the same wall you have sockets that are at diff heights.
If there was a purpose for the socket to be heigher or lower then the rest (ie for a flat screen tv), then its understandable, but as a rule of thumb I think we ought to be asking/telling our customers to be standerising heights.

You're misunderstanding the concept. You're correct that we are the designers and to have pride but, you're also in the hands of the client who doesn't have to listen to your points about socket heights if it costs extra money/doesn't want it done

If you feel that strongly about it you could always turn down the work

 

[Mad Spark]

Totally agree fuzz, however i feel what I'm saying is still relevant, yes the customers are all different some have very deep pockets, and some have very tight purse strings, so we are in a bit of a nightmare scenario, but we have to try.

For me anyway, every rewire I have done to date I have spend extra time and effort in bringing sockets/switches to the new heights.
it has taken a bit of persuassion on the my part but when i mention what needs doing to the customer, they luckly have agreed without much hesitation.

you can tell instantly who`s who..in the deep pocket situation....but as i see it..it doesn`t matter either way....the standards of work/install....together with all relevent tests and the paperwork to back it up should be consistant.......this is what gets my goat about cowboys......

Well that's what I always did.

It makes it look like a proper job done by a proper tradesman.
