H=DD
How can I decide that a circuit is a limited current circuit or not
before making any current measurement?
And can you give me an example what kind of IT equipments generally
has limited current circuits.

I think that any circuit with a voltage source and some resistance/
impedance in series with the voltage source before it is accesible to
the outside would be current limited. For instance, a 5V source with
a 1000 ohm resistor in series with the lead going outside the cabinet
would be current-limited to 5 milliamperes.
