Ah! Well my Zappi was tested by me plugging in the car and seeing that it started charging ... 30 seconds later the guys were gone!
Not unusual, but frankly wholly unacceptable. It's mandatory that a functional test is performed, as, apart from anything else, the functional testing makes sure that the built-in safety features (could well be life-saving features) are all working correctly. These checks ensure that the contactor opens and isolates power in the event of a range of faults that might occur, including things like the connector being dropped in a puddle, etc.
This is no different to the mandatory functional testing that must be performed on any outlet, to check basic stuff, like the L, N and PE all being wired correctly to the socket, that the switch functions to turn the supply off, etc.
The test box I have has a Type 2 vehicle connector fitted to it, plus four switches for functional and fault simulation, and a 13 A outlet so that a MFT can be plugged in to check that everything is OK at the end of the cable. This also allows normal tests to be conducted, in exactly the same way as any other 13 A outlet in a house would be normally tested, both following installation and for routine periodic inspections through life. Without such a box it's not possible to sign the installation off as being both functional, and far more importantly, safe.
