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

Equipment manufacturers are starting to use 20amp IEC inlets on their gear because it is a more solid connection than the 15amp IEC.
You guys are making a mountain out of a molehill. The reason some 15A audio equipment is using the C19 connector is exactly as I said previously - because it's a more solid connection.

First I would bet the cord is not listed by UL or any other recognized testing agency.

Jea48, how much do you want to bet? :-)

I am looking at a box full of about twenty NEMA 5-15p to IEC C19 cords that are UL and CSA listed. The computer industry has been using them for decades.
Where is the protection.....
The cord and plug is not idiot proof, jmho.

I agree that it's not idiot-proof, but I'm not sure that it matters. How many threads have you seen here and on other forums where chooses (or advises someone else) to do something blatantly foolish with electricity or electrical connections in the name of audiophilia? How many times have you heard some audiophile say that the NEC is too cautious or just plain wrong? Way too many times, I reckon. Make something idiot-proof, and a more resourceful idiot will come along.

Anyway, the saving grace (pun intended) is that there are almost no consumer audio products that actually need more than the rated power of a 15A convenience outlet. The few that do that I'm aware of have hard-wired power cords. You'd have to saw off the factory plug and put a NEMA 5-15P on there in order to plug it into a 15A outlet.

I had it built for 240v... How much current (I know that is a big word for some of these forum pontificators) do you think a 5x200 amp will draw as it sees lower and lower impedances?

When playing multi-channel music or movie soundtracks, the real-world max current your amp will draw is between 5 and 8 amps at 240v. That's full-tilt, all channels active.
