So you have wires from the power supply to a USB socket, then are using a USB cable from the socket to the iPad?
Is this USB cable a quality cable rated for the power the iPad will draw?
Lots of USB cables use very thin wires. You need one that is rated for the current the iPad will draw. Do you know what maximum current the iPad draws?

How it\'s wired. With my wiring, the USB wires are heating up to around 200-300F.
Am I using the right voltage?
A VOM seems like the easiest way to VERIFY that.
You may find the PSU requires a heavier load on the supply than you are
providing.
Putting an ammeter in series with the load to give you a rough idea of
the amount of current flowing would be a good idea. Likewise, the voltage
DROP across the cable\'s length.
Is the iPad demanding too much power? The PSU worked fine after the incident.
iPad get warm (battery)?
If you disconnect iPad from your \"adapter\", there should be NO current flowing
and no \"heat\", right? (i.e., wiring error)
iPad battery is OK, it\'s the USB wire that gets hot,
The battery may not be OK for long!
Why not use the right iPad charger?
