EV Mode 2 charging O-PEN

Because they can be installed with a TT or TNS earthing system, but if you want to install them to a TN-C-S earthing system you are going to want the O-PEN protection.

Edit- I replied whilst eating a cheese sandwich in a lay-by alongside the North Devon Expressway before getting onto the M5, as you do.

I am sure that the manufacturers will tell you that Granny Leads can be used quite safely with TT and TNS earthing systems, as well as indoors with TN-C-S earthing, therefore they are fit for purpose when used appropriately.

But as a knowledgeable person you are going to want O-PEN protection if using the Granny Charger outdoors with TN-C-S earthing, but if you are going to fit that in a fixed installation you may as well go the whole hog and fit a 7 kW EVSE unit with the O-PEN built in rather than use a Granny Lead.

Mode 2 is a cable with an RCD in the ICCB and a standard plug on the end, not a fixed Charger. so they can be plugged into any standard socket.
