Safety, Functionality and Aesthetics - continuing





Question





 



In my formative years electrical, I was brung up that an isolator for a cooker etc must be nearby, say within 2m and obvious as for useage (or clearly marked) as a readily available "rapid use switch" in case of say chip pan fires etc.

. . .

Modern folk and their kitchens, it seems some folk have an aversion to them.


Call me old fashioned but my order of preference is 1/ Safety, 2/ Functionalability and 3/ Asthetics.


Any views on this Folks?





Ebee's original post under the heading, "Cookers, Isolators and the Like" inspired me with an idea about aesthetics. Rather than extend this long but interesting topic, I decided to continue the idea as a new topic.


During a period when I was working for a consulting firm, I had an argument with an architect. In some dressing rooms adjacent to a theatre-style set-up, I had specified some power points over the dressing tables, to serve hair-dryers, etc. He objected to this position on the grounds that they were unsightly, and wanted them low down, out of sight, below the tables. I argued that this was inconvenient for access.


The architect won, of course; he that pays the piper calls the tune. This incident and similar ones have led to ongoing discussions.


"Wiring accessory manufacturers go to great lengths to make their products aesthetically attractive, and sometimes win Design Centre awards. Why are they commonly regarded as unsightly? In any case, we are happy for light switches to be placed at convenient height, so why should power sockets be placed low down where they can become obstructed by furniture?"

     "It is not a case of the sockets themselves being unsightly. It is the flexes that trail down from them."

     "We do place sockets a metre above the floor in old people's homes. We don't like to think of elderly people falling because they need to stoop low."

     "Yes but in any dwelling there are likely to be elderly people in residence from time to time. And in care homes, plugging and unplugging is usually done by staff; residents are not encouraged to do this."


So it is down to a trailing flexible lead being not aesthetically attractive, and I do agree that this is a point. Consider now the colour of the lead and compare black with white.


Walls tend to be light in colour so a black lead stands out more conspicuously than a white one, and we can make a case that a trailing black lead is more unattractive. So white is better than black.


A lead may also need to be laid on a floor for a certain distance. It makes sense to keep it tucked against the wall, but this is not always possible. Flooring materials, (carpets, floorboards, etc.) tend to be dark in colour. So a white lead is more conspicuous than a black one. There is a safety issue here; a lead on the floor can be a trip hazard so should be conspicuous. So again, white is better than black.

DIY stores stock flexible leads usually in white. Bronze may be available for certain appliances with which it tones in well, but I rarely see it for sale in black. That's fine for me.


So why, oh why, are most electrical appliances sold with black leads? It seems to be the universal standard for audio-visual equipment. Even our vacuum cleaner, which trails a long lead as an occupational hazard, has a black lead. Only a very few appliances have a white lead - like our fridge, which has its white lead tucked innocuously between the wall and the appliance and rarely moved.


It seems therefore that the wide usage of black leads has influenced the placing of power sockets low down, with the attendant safety concerns. Has there been lack of joined-up thinking here?


Any view or further discussions on this?

    I`ll bet there`s plenty of those old metalic irons about with twisted cotton covered 2 core flex with a BC lampholder connection for ironing shirts using the lighting circuit and some have the luxury of a BC Y splitter so you don`t need to iron in the dark.


    I saw quite a few as a kid but not many piles of dead bodies


    Yes, Ebee, we once had an iron like this; it originally belonged to my wife. It worked, but I decided I did not want even one dead body, let alone a pile, so I sent it to WEEE recycling.


  • Denis McMahon:

    The quaint old days when a TV set had two leads, one for the power and one for the aerial, are well in the past. One of our TVs shares a stand with a video tape recorder, a DVD recorder, a digital-analogue converter and a hi-fi sound amplifier. This results in a plethora of interconnecting leads - difficult to keep tidy. The only white leads present are for the multi-way extension which powers this lot, the aerial and the ethernet cable.


    Well, I like my CRT tellies and they will go only when they pack up. One of the biggest problems has been the longevity of Freeview boxes - pity about them!


    We had a B&O telly installed a few years ago and all the cables were put in a neutral-coloured sock, which tucks in at the bottom of the skirting boards. AFAIK, the current version uses bluetooth for the speakers, so that is 2 fewer cables. It probably also gets its signal by wifi, so that's another lead gone. What cannot be avoided, but what could be out of sight if the socket is carefully placed, is the mains lead.


    Which reminds me of a story and if I got it from here, I apologise for the repetition.


    A woman took some wall lights back to B&Q.

    Customer: these lights don't work.

    Sales assistant: have you tried them?

    C: yes we put them on the walls, but they still didn't work.

    SA: did you get an electrician to connect them?

    C: no, aren't they wireless?


    The sad thing is that it has a ring of plausibility about it. 


  • Mention of "clear, figure of eight, unsheathed flex, of ancient memory:

    What was the insulation made of?

    Recent clear out revealed a short length of it 60 years old!

    It had not aged at all. Just as flexible and clear as new.

    Was  it a wonder material?

  • On a security issue here:

    How do we logoff? Where is the button?

    I does not time out if I leave the machine and it goes dark on its own and I don't power it off completely.

    Not a good habit perhaps but it can happen.

    On my desktop computer, the log out function is in the pull down menu, top right of the screen, little down arrow in a sqare box.  Next to the bell.

    Not just plausible, I know someone who has wireless LED picture lights.


  • wireless in that they have a battery and are turned on and off by radio, perhaps ?
  • "wireless" now there`s a term.

    When I was a kid my grandfolks ( and often my parents) called em wireless, meaning a mains radio, before the TV era and well into it.

    Us kids were smart and called em radio whether mains or battery.

    Nowadays we all call em radio but the new tech stuff such as wifi etc we call em wireless.


    Circles of fashion?
  • Well ebee, wireless always has meant "without wires", as before radio the only way was with wires, as in telephone. Wireless communication is radio, wireless charging is not, it is magnetic induction, which is a bit different. Transmission of significant power without wires is a very short distance thing, although Tesla hoped to find a way to do it. Radio signals are often very weak, your radio receives a few billionths of a watt to operate (-60 dBm), although the transmitter may be many kilowatts or even a few megawatts. It's all very strange, isn't it?
  • Hi Denis McMahon


    Last week you asked a question in our Wiring and the Regulations (BS 7671) forum.


    Don't forget to pop back and help our community members by selecting the 'Best Reply' or to mark your question as 'Answered'!



    E-mail I received from IET Online Community Team.


    Well I am not sure how to select a "best reply", but I've "liked" one.


    Unfortunately nobody really answered my question. Some replies focused on safety being paramount. But my point was that in this case, safety, practicality and aesthetics all pull in the same direction. White is best and black is worst so why is black so common?


    Thanks, nevertheless, to all that contributed. You made some interesting points.


    As for the question, I guess it remains one of a collection that I'll take to my grave.
