What makes a 20A IEC rated for 20 amps?

What makes a 20A IEC rated for 20 amps?
I now the blades go in a different direction but are the blades thicker to carry more current?
I ask this because I have a component that I am demoing that has a 20A IEC on the back. I have some pretty pricey power cords available with 15A Furutech NCF fittings. A 20A Furutech replacement 20A IEC connector sell for almost $300! Or I could always use a 20-15A IEC adapter. But that would add a (cheapo) connection.

So how about if I just change the IEC in the unit to a 15A Furutech NCF about $80. Hence the question.

Elizabeth,

Thanks, I agree.
About the change in size on the Furutech, I found this out the hard way...

After talking with a few Audio friends, we concur that probably the reason for the 20A IEC on the back of some component is to ensure that whatever power cord is plugged into it can handle 20 amps and consists of 10-12ga wire.
That is; all premade 20 amp power cords that I know of do come with substantial internal wiring.

Of course anyone can put a 20A connector on any cable regardless if it has 10-12 ga wire inside. Then, there are the 20/15A adapters we use, who knows what type of gauge is used with them.

My new Inakustik AC-3500P power conditioner that is rated at 15A comes equipped with an IEC inlet rated at 20A. According to the dealer, that inlet is better at supporting cleaner power surges than an IEC inlet rated at 15A.
