... the real reason for using a 20A plug is to prevent someone plugging something that draws 20A into a 15A standard receptacle and overloading the circuit. There's nothing in the design of a 15A plug that makes it unsafe carrying 20A provided the circuit its connected to is rated 20A.Absolutely agreed. My suggestion to use a cable with a 15A plug on one end and a 20A IEC connector on the other was only intended for components that draw less than 15A, such as ARC preamps. In practice, if that cable were used on a 15A line with a component that actually could demand 20A, the circuit's fuse or circuit breaker should trip. But it's bad practice to rely on a safety device in that fashion.
