It’s ac so shouldn’t make any odds?

there’s a convention I think and you can buy that lead it’s called a figure 8

If it is AC then of course you're right. But it's a funny looking sod - doesn't look like any generic figure 8 connector I've ever seen, with the flat on one side

It’s called a polarised one. An ST7 to be pedantic!!!

it seems to be a European / usa thing.

Buy a figure 8 lead and file a flat on one edge?

It is a USA thing. Long ago they had no separate ground wire and the Neutral was used as ground on portable appliances - i.e. body/case/handle wired to Neutral! Thus the original poxy 2-flat-blade 110v power outlet had to be "polarised" to ensure the metal case of an appliance did not become Live.
This polarisation will only be valid if the power cord is permanently attached to the appliance, or if the attachment cannot be reversed. Thus a true Figure-8 lead needs to be polarized ( even tho' nowadays most appliances are double-insulated ).
