External 3 phase sockets (pme supply)

I'm 'morally' in full agreement with you, but it cannot be denied that the wording in the BGB is (for a change!) fairly clear on this. It's actually made me wonder about all the times I've been asleep in my bunk on a tour-bus whilst it's been parked up next to a venue on 'plug in', as well. As I can tell you now, when a bus driver see's a 32A outlet he's not in the slightest bit bothered about just plugging up into it!

You would probably be correct when talking about a gig tour bus from your past... lol!!
But a refrigerated van/lorry parked up over night, ...Nah!! lol!!

Say it was a tanker delivering XXXX. Normal practice is to solidly connect the tanker to the delivery pipework before the discharge pipes are connected. Makes a total mockery of making the trailer supply TT.
I’m surprised anyone even contemplated it in the first place.
