TIA568 Wiring Standards

How to decide which wiring pattern to use:

1. Does the job specification call out a wiring pattern?
2. Does the customer/end user have a preference for T568A or T568B?
3. Have patch panels already been purchased for the job? If so, they will probably be either T568A or T568B. The jacks should be wired to the same pattern as the panels.
4. Are you adding on to an existing wiring plant? If so, your new wiring should match the existing wiring.

If none of the factors above apply, either T568A or T568B may be used. It is important to ensure that the workstation connectors and the patch panels are wired to the same pattern. T568B is commonly used in commercial installations, while T568A is prevalent in residential installations.

BELL Series

Bellhanger's bits feature a high speed steel bit, or a Carbide/Masonry bit, mig-welded to a 1/4" hardened steel shaft. Available with or without crossbore to allow the user to pull wire. The 118 degree point allows a gradual breakthrough, leaving a cleaner bore. High Speed Steel bits drill in metal or wood.
