Electrical Question - dumb one - but a good one


I am looking at an amp that has a 20 amp iec connection. I realize that my current power cord will not work - and I'm looking into have that '' retro-fitted '' with a 20 amp iec connection.....My question is ; '' the connection end at the wall - does the wiring, recepticle have to be changed because the amp end is now 20 amp iec, or does that stay the same and is okay as is '' ? Thank you.....

The power consumption of any electronic device is in VA.
This is corrected for power factor.
You get BILLED for watts, or KWH (kilowatt hours) but consume VA, which except for a resistive load is always higher. Power companies will bill large, typically industrial users slightly more (surcharge) for such low PF loads.

What does the plate say on the equipment? In general, I'd be reluctant to convert a device with a 20amp connector to a 15 amp service. If this is a large power amp with 'ample' capacitance, you may get a pretty good turnon surge, even if you never crank it up or have higher sensitivity speakers.
