AS/NZ standard state 568A should be used. A lot of patch leads imported from various places are wired 568B, and there is no issue with that, but permanent cabling should be wired 568A to reduce confusion.

Lets be honest the NIC is colour blind so it doesnt give a rats &rse.

sonyxperiageek: Oh, and if I was connecting the Cat 5e/6 cables, would I follow the T-568A or the T-568B here in NZ?

Thanks.


568A.


Doesn't it depend on the cable?  I've seen both 568A and 568B labelled on cables (no the same cable obviously).


I assume you have seen this marking on premade patch leads. It is the same cable type used for both A and B leads, just with a different pin out at the RJ45.

cyril7: ELV (and TNV) to LV?, Legal requirement, punishable by removal of electrical registration is 50mm or a solid permanent insulating separator. Recommended 300mm minimum for interference mitigation.

Not trying to hijack this but it got me thinking about wiring my father in law has had done in his house.

There are a number of places where the sparky has put power and cat5e through the same hole (going from one floor to another, or through a wall) so he didn't have to drill another hole. After going through the same hole it is seperated. At the time I thought it was just lazy work and even made the comment to him.

Whats the standards on this?

Hi, its illegal the electrical standards AS/NZ3000-2007 section 3.9.8.4 Section (c) details this and to put both through a common hole in a top plate, stud, noggin or floor is illegal.

Currently the Electrical Wiring Board is persecuting electricians that flaunt this seperation ruling.
