Arctic Cable

[ian932]

Hi,When is arctic cable used for domestic?

Thanks

Its used a lot for wiring leisure crafts (boats etc) and caravans as they have to be wired in flex and not T&E and it deals with the winter storage temps well.

Its also used to make hook up leads for the above, I do a bit of marine and love working with the stuff, it beats T&E on a cold dayheadbang

it would be fine I suppose to use twin and earth, as long as you isolated the earth at the moon end and made sure it couldnt come into contact with moon in anyway whatsoever.the potential difference between earth and moon would be much greater than earth and true earth mass and I very much doubt the CPC would carry the fault current.

I think a TM system would be required in this situation, perhaps with the addition of an additional satellite spike if required to get the necessary MLI reading to an acceptable level,

remember though that the MNCS is still not an acceptable system for the garage.

Blue is normally for 230v and Yellow for 110v

Although there is nothing specified in any standard for that, contrary to what I've heard claimed by some people. I think they're getting confused with the blue and yellow BS4343 connectors.

For something like a caravan hookup lead, I always use yellow, since it's more noticeable when trailed across grass etc.

... and what type of cable would you wire up Uranus???

Not sure about the cable type, but the ends would need to have ring terminals. ; \

I know what your saying but 99% of leads which you can purchase with these connectors attached normally have the same coloured lead.

Agreed. I wonder whether that's why many people have gotten the idea that the lead color is somehow part of the standard?

I'm not 100% sure, but I believe that on construction sites, the HSE has decreed, that 110V leads must be yellow.

I seem to remember something about it when I did my H&S test for my ECS card.

 

[PBC_1966]

I believe that on construction sites, the HSE has decreed, that 110V leads must be yellow

Presumably on the grounds that as the primary leads being trailed around all over the place, yellow is more noticeable?

But conversely, have they decreed that yellow is not to be used for other voltages?

 

[spinlondon]

Found the book:

"Yellow is the usual colour of cables, socket outlets, plugs, transformers etc which are used with 110 volt supply."

Doesn't actually say must or has to be yellow.

Think I'd go with the above, more of an HSE thing than an actual standard or regulation. Only time I've ever seen it stated that 110\240 leads are one colour or the other is in ECS exams.

If it was a regulation or standard then you wouldn;t be able to buy yellow 240V leads in Wickes etc... I have a couple of 240V yellow arctic leads for the garden, would be frowned upon on site though.

Why though? It's not as if you could plug a 110V power tool into the blue 240V connector on the end or anything like that. And what colors would be "non frownable" for 3-phase 415V leads?

Thinking about hookups on campsites mentioned earlier, I do recall reading one story about a site manager who tried to complain about somebody using a yellow Arctic lead, insisting that there was some sort of rule that only orange was permissible (whose rule, I have no idea).

I don;t know, ask the HSE.

And what colors would be "non frownable" for 3-phase 415V leads?

I wondered that, they are never mentioned, perhaps red, or black, or whatever colour you want, or don;t use 3 phase extension leads. Again, there's nothig stopping them being used AFAIAA, but the HSE may be against them for some reason so haven;t mentioned them in the guides and exams.

The connectors are red but since atric isn't midly available in anything but yellow and blue I guess the cable would be one of those?

 

[PBC_1966]

Exactly. I know red Arctic is made, but it's nowhere near as common as blue and yellow. I can't see any logical objection to using yellow for 240V, and especially not if either it (or "240V blue" Arctic) can be used for 415V.

But then I wouldn't ever expect logic from the HSE these days.

As a side note I notice in PE today they have a write up stating that there is a crap batch of Arctic flex on the market, thats come in from foreign shores again.

Blue and Yellow come in 3 core (brown, blue and green/yellow) you would need a minimum of 4-core for 400v

 

[Lurch]

Well no, you could have 400V 2 phase.

SY or H07RNF is normally used for 3 phase

So if Badge wants to run his xmas lights below +5 degC he will need to use yellow artic and run them at 110V.

Wierd how TLC claim both their yellow and blue artic goes down to -20 degC but neither claim BS numbers.
