three phase power points- cheap and easy solution in the regions

@bje​ you're right. that's even better -except it would be more expensive to install this type of outlet and they would have to engage with a specific supplier to install it and if it became faulty or was damaged it would require a specialist repairer. etc.  whereas a three phase power point can all be done by an electrician. it is totally serviceable. nothing expensive or complicated.

An un-tethered socket like the one shown can be installed and repaired by a licensed electrician. No specialists required and equally serviceable.

but the outlet and frame etc would have to be sourced from a specialist supplier while a 3ppp can be bought from a standard electrical supplier. also a 3ppp would be cheaper to buy and cheaper to replace. there is no complexity or circuitry with a 3ppp. it is so basic and simple. also a number of them can be placed in a row so that congestion can be avoided. also extension cords exist for ev's with odd inputs. 3ppp testers are also available for fault diagnostics. the benefits are indisputable. 

Hi @George_m. You've not addressed the requirement for every car using these 3 phase power points to have a single phase or 3 phase portable EVSE with a 5 pin plug. That is a lot of cost to place on the entire set of people wanting to use such charge points. Most people have a type 2 cable already.

yes there is a one off cost for this special cord. approx. $1300. 😳 which is really expensive. but it would open up the usage and convenience of the 3ppp. i would get one asap if the 3ppp adoption was rolling out in haste. and because the 3ppp would be a relatively inexpensive power outlet for the host to set up then the usage cost may be low too. with complicated and costly type 2 chargers the host has to charge as much as they can to recoup their costs and maintenance. also if the adoption of the 3ppp were to become the norm then a manufacturer may come up with a thingy/adapter that plugs into the 3ppp and allows us to plug our type 2 cord into that therefore reducing the cost. also a point worth adding: the 3ppp would be mostly implemented in the regional areas where more people are aware and familiar with the 3ppp. much more than they are familiar with the type 2 Schneider charger for example. this is a huge deal as familiarity is a major advantage to acceptance and understanding and decision making.
