Flexible cord is not to be used where a permanent wiring system is required, except under certain exceptions. The concern is that flexible cord is not as robust as wiring in conduit or wiring in walls, and over the long-term exposure that permanent installation implies, a flexible cord could become damaged and hazardous.

Don, Hi. In your response to Brian you said... " However, written into the body of the IEC 60950-1 and EN 60950-1 (and other national derivative standards) is a wiring method for permanent connection to the mains not acceptable in the US and Canada – the use of a non-detachable power supply cord for permanent connection. " Can you please supply to me the reference that prohibits that wiring method in US and Canada?
