How do these chargers get wired up?

Recent situation got me thinking about EVs (with all the memes going around).

For example dual charger

With regards to dual chargers, do they have two incomers going into them or is it just single cable capable of supplying both connectors ? 

Just curious.

  • The only one that I have seen up close had a single cable to supply both charging outlets. Three phase 32 or 63 amp according to charging capacity. 

    One cable is probably cheaper to buy, and certainly cheaper to install than two.

    Use of two cables would add to costs and make safe working doubtful without isolating both.

  • I've not seen the innards of that particular one, but judging by caravan hookups and other high current equipment (e.g. hobs) I'd sort of expect a set of terminals that could be connected or bridged in a number of different ways - e.g. for one single phase circuit, one two lines of a 3-phase circuit or possibly even two separate single phase circuits - as whatever suits the installation best.
