Rex, has it right and in the proper perspective. Even if one's amp is pulling 1200 watts, that is 10 amps current. At turn on or start-up the amp might 'pull' more amps to charge the capacitors, but then that is for a 'miili-second' and no cause for concern.
20amp IEC connector with a 15amp plug PC? ??
I m puzzle what is the difference between a PC with a 20amp IEC and one with 15amp IEC but same 15amp plug and drawing from the same circuit? Noticed most PC with 20amp IEC are sold with 15amp plug. Currently using a power amp which accepts only 20amp IEC. TQ you in advance
