20amp IEC connector with a 15amp plug PC? ??

Jea48, CJ350 stock PC comes with a 15amp plug.
It doesnt make sense. As far as I understand it , shouldnt equipment with need a 20amp IEC comes with a 20amp plug which rightfully should be connected to a 20amp dedicated circuit with 20amp circuit breaker to maximise whatever current the equipment need?

The only logic I can think of is that most house wiring is basically 15amp circuit with 15amp circuit breaker, hence, the 15amp plug. Happy listening

Audioblazer,
to add to the confusion.......

Note the IEC 60320 C13/C14 is rated for 10 amps. And the IEC 60320 C19/C20 is rated for 16 amps.

Got me at a loss.......

Perhaps the 20 amp IEC is for marketing. Perhaps there are very few components that actually consume "20 amps".

Note the IEC 60320 C13/C14 is rated for 10 amps. And the IEC 60320 C19/C20 is rated for 16 amps.

I spent some time looking at sites on Google. From what I have gathered in Europe the C13/C14 has a listed rating of 10 amps. It appears here in the US and Canada the connectors have a UL and CSA listed ampere rating of 15 amps.

The C19/C20 Europe 16 amps, US and Canada a UL and CSA listed ampere rating of 20 amps.
Example, note in this ad the UL/CSA at the side of each connector and the spec info page.

I assume the CJ amp is UL and or CSA listed. If so the equipment was tested and found that it did not exceed an FLA, (full load amps) of more than 12 amps. That meets the minimum plug that can be used on the cord of the equipment.
CJ could have supplied a cord with a 20 amp plug but imagine the complaints from the consumer. The damn thing won't plug into my Oyaide receptacle.....

You the user can step up to a power cord that has a 20 amp plug if you wish. What you should do is make sure the conductor, wire, in the cord is at least #12 awg gauge. Make sure the IEC female connector fits tightly into the male connector on the back of the Amp. Poor contact pressure causes arcing. Arcing causes noise as well as heat and voltage drop.
Also for your amp a dedicated 20 amp circuit with a good quality receptacle. Just a note here on receptacles. The guts inside a good quality recept use the same 20 amp rated contacts be it 15 or 20 amp..... Only the faceplate is different. It's an NEC safety thing as I described in an earlier post.

Wire size for the 20 amp branch circuit? Minimum of #12 awg. In your case if the total run is more than, say 30' to 40' I would have installed #10 solid wire. Jim
