The current rating is based on overheating if the specified current is carried continuously. A 15 amp rated plug will handle any current surge that your amp will demand just as well as a 20 amp plug.
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.....
