    Default striped wire +or - ...Cat 6 A or B

    I always considered the stripe on fig 8 wire to be negative however whenever I search online there is a conflict of which is which. Some say stripe is positive some say negative. Is there an accepted international standard for DC identification.

    So long as you are consistent either has been acceptable as long as I've been working with speakers but I've always used the stripe as Negative

    No standard that I have ever come across, can and is used both ways.

    There is a divide in convention between hobbyists and professionals. In professional audio and telecommunication applications a coloured, marked or striped conductor is almost always the 'hot' (+) or 'active' wire of a pair, in fact I don't recall ever coming across and exception to this rule; in non-professional circles the marked or striped conductor is commonly ground or (-) with an exception if the marking is red.

    Being from a professional background, I always use the physically striped side of a figure-8 cable as the hot or (+) conductor. On a grey cable with a black strip, I'm somewhat conflicted, but would probably use the black striped side as (-).

    I have always gone with stripe is negative but did a Video Conference install course a few years ago and they taught the opposite.
    At the end of the day it does not matter if you are terminating both ends of the cable just use the same pattern both ends. And if it is someone else's work put a meter on it and check.

    True story. I was working on the IT fit out of a new building and the alarm installers were there at the same time. I saw them turn the panel on and lots go wrong, turns out the two installers that don't normally work with each other were using different colour codes.

    I was taught the stripe was always the "hot" or positive, would have just been easier if they put a red stripe on the cable instead of a white or black one.

    I have always used B, I believe the A is a carry over from the US govt, and everywhere else uses B.
    As there is no technical advantage of A over B I don't know why they even made B a standard

    And then there is green garden cabling where one side of the HD zip wire has a square edge and the alternate side is rounded.
    I've recently started using colour coded shrink wrap on my banana plugs because in the low light conditions I can't tell the difference on small terminals markings.
    Wall internal wiring does use colour coded conductors but I guess that the important thing is being consistent

    Interesting answer, I was working with a cabler a while back terminating a heap of sockets and asked him what he uses A or B and he said he just uses A for Australia.

    No technical advantage, just make sure you terminate both ends to the same standard. A cable with A on one end and B on the other is a cross over cable, rarely needed now.

    And I normally use B, the one that starts with orange/White.

    B is the carry over from the old US phone system colour coding specifically AT&T.
    I believe the US Govt mandate the use of A for its systems.

    Does it matter, just how this bloke remembers it as it appears there is no standard just your standard and his standard both different but achieve the same result.

    so let me get this straight, when connected the internet from Australia to Belgium, you should use a crossover cable as that's A on one end and B on the other
