Did you know .....

[SLIPSHOD & SLAPDASH]

Just found out something i never knew (from section 740) Circuses are spelt circuses.

And 753 comes after 740, its obvious isn't it .

Hi , I'm new and thought I would introduce myself with a few generally unusual reg facts, please feel free to add your own - or even tell me mine arn't that uncommon knowledge . here goes .....

Welcome to the forum sb_89, I would say that the things you mention are not that uncommon as many of the NICEIC guide books, snags and solutions books and other similar publications have been around for a few years now. What one considers unusual will be proportional to the number of years a person has been a practicing electrician and the type of installations they work on, commercial, industrial, domestic, petrol stations, agricultural etc, as they all have their own quirks and specific regulations. Anything relating to Non-Conducting locations is going to be unusual 418. But personally I don't see much productive point in discussing the regs that people rarely have to refer to?

If I were to get a length of copper pipe; cover it, in its entirety, with brown coloured lagging, and use it as a live conductor.............

Which (if any) regs would it be in breach of????

n.b. Does anyone know the ccc of 15mm copper pipe (to table "Y").

Thanks

Do you mean inside and out?

Could we use it to supply your showers water/electric (combined) supplies?

Well.....

If you were using it as a 'Neutral' live conductor rather than a 'Line' live conductor..

could well not comply with 514.3.1???

OR...

if you 'lagging' is not up to a suitable standard of insulation could also be 412.2.1.2 / 412.2.1.3?

`Tis done

Nozzer - Now THAT idea has merit - think of the savings in cable. We can even fit a pushfit it isolate this bit of copper from the rest of the house!!!!

Oh, buggrheadbang I`m going to delete this - some wazz will try itbad day explode

 

[NozSpark]

...and use a pipe clamp for the power connection:O

Is that Concentric?

water inside...

lectrix outside?

:innocent

 

[steptoe]

you speak in jest,

many moons ago I was working on a farm and such a supply existed, (albeit minus the water though),

2runs of 1/2" pipe nailed to wooden blocks about 2" apart with croc clips on both ends running down the side of a cattle shed for a temp supply to a new building!!!

I was just starting to serve my time and had no idea of the implications of such an arrangement at that time,

if I had known I would have had a stern word about making sure all the joints were soldered to code and not these silly compression fittings!

if its 'water cooled', then you may be able to run it at a higher current than empty

 

[sprocketflup]

What an excellent idea !

You'd end up bonding the electricty meter

 

[Evans Electric]

well evans , tell me something i dont know? it was only ment to be for fun , i thought people could add to the list maybe. BS 7671 is an extensive book, you cant retain everything and there will be somethings covered in it that you will probably never come across for example, i have never came across a VOELCB and i wouldnt of known how to test , id of referred to the book ....[/quoteSB Glad to hear its only in fun , can't always tell from the text, hence the use of the

things.

Some guys get all tied up with the Regs and will spend 2 hours consulting the Regs and the OSG and 5mins replacing the broken batten holder.

Others can quote them verbatum but can't make a Pyro end off.

Has anyone done any of the BRB wonder sections ?

Mobile units 717

Amusement devices /booths etc 740

IT systems

TN-C systems ( Oh yes I've done two of those)((Wierd)

 

[sb_89]

ahh the fabled TNC system .... where on earth did you come across that ? am i right in thinking that the nuetral and earth are connected thoughout the electrical installation ? I have never seen 1 .. and never met anyone else who had

IIRC, years ago a national chain (M&S?) used to be wired in 1 core pyro. never came accross it myself, apart from when someone has used a bit of straight con as a submain because the DNO left some spare....

 

[NozSpark]

I've had someone lay about 25m of straight con (alloy core, copper outer) and then expect me to hook it up,,, well the DNO laddie said it'd be OK:O
