Why do they need a plug & socket?

If it is simply for a means of isolation for maintenance then a lockable rotary isolator next to their box would do and then no RCD needed.

A lot of the recent new doors I've seen come with commando plug already fitted, it's like they're expecting them to fail and it's easier, and cheaper, to send cheap labour just to swap it over rather than a spark to mess with silly things like wiring...

Seen one which was fed from a 16 amp commando which was plugged into a standard BS1363 socket outlet... ?

Ah, follow the money and you see the reason

Externlising the cost as they say, making your installation more expensive to overcome their crap quality.
