Wow, that means there is a lot of false information on the Internet. There are a lot of sites that say 568A is
required for any work done under a federal contract. Here are 3 of many examples:
The Difference Between the TIA/EIA T568A and T568B Wiring Standards
TIA standards, testing Category 5, T568A versus T568B
What is the difference between T568A & T568B?
Federal contracts are written by people who have no flippin' clue what they are talking about.
(OK that might be an over-generalization, but just my personal bias and experience talking).
I have seen while searching the same thing, that "it says to use 568A for federal contract work", but, I personally have not seen it executed (not to say it doesn't exist, it's a very very big fed).
I just had to piece together parts for a "standalone/shielded" network installation because "they" worded the contract wrong, and that portion of the network project was never installed. Half the parts I was given were not correct either. Unshielded patch panel for a shielded network. Wall boxes not deep enough or large enough to accept the Keystone jacks, crappy connectors etc.
"Just make it work if you can make it work, I will accept responsibility" is what I was told by the project mgmt. Keystone jacks are smashed up against the back of the wall boxes, bent up at 90* angles. Barely holding onto the edges of the faceplates, trying to keep from popping out. The one thing I would not budge on is terminating it down to the unshielded patch panel.
"Good enough for government work" is not just a saying unfortunately.
All that to say just use 568B. Dang near anything you run across is going to be wired 568B, to include any pre-terminated cables you buy (yes you can run A-A with B-B, but still).
