You can use your already installed 15 amp breaker... no problem.And NO you cannot just stick in a 20 amp breaker to replace the 15 amp breaker in the box! The wires in the wall must be a certain size to use a 20 amp breaker.
As others mentioned the IEC is just for more area to allow good transfer of AC power.
For the state of the art stuff, yeah you would want several 20 amp lines. For mere mortals, a 15 amp will suffice until you decide to upgrade some more..
