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.

How To Find Voltage And Wattage Ratings On Your Appliance

To determine the correct model voltage converter or heavy duty transformer you need, you must know the voltage and wattage requirements of your appliance. You can find this information listed on the appliance manufacturer's label located on the back or bottom of the appliance or in the specifications section of the appliance owner's manual. The label or manual will show the input voltage (100, 120, 220, 240 written as: 120 volts, 120V, 120 volts AC, or 120VAC), the wattage (100 watts or 100W), or the amperage (0.5 Amps or 0.5A or 500mA).

IMPORTANT NOTE:
If only the amperage rating is shown, multiply the input voltage by the amperage rating to find the wattage rating.
Volts x Amps = Watts
or 110V x 1.5 A = 165W
This is also written as 165VA

Cycles - 50 Hz vs. 60 Hz

North American 110-120 volt electricity is generated at 60 Hz. (Cycles) Alternating Current. Most foreign 220-240 volt electricity is generated at 50 Hz. (Cycles) Alternating Current. This difference in cycles may cause the motor in your 60 Hz. North American appliance to operate slightly slower when used on 50 Hz. foreign electricity. This cycle difference will also cause analog clocks and timing circuits that use Alternating Current as a timing base to keep incorrect time. Most modern electronic equipment including battery chargers, computers, printers, stereos, tape and CD players, VCR/DVD players, etc. will not be affected by the difference in cycles.
IMPORTANT: Voltage converters and transformers do not convert cycles.
