EV Mode 2 charging O-PEN

A few weeks ago I had a conversation with a guy who knows about these things.

I said that one of my neighbours wants a socket on the front of his house for cleaning his car with a vacuum and pressure washer, obviously it could be used for a Mode 2 charging lead aka a Granny Charger, so what precautions are required as the house has a TN-C-S earth.

The advice I received was to just get on and do the job, because really it’s just another socket and if it wasn’t there another one would be used anyway.

I have not actually done the job yet as I keep getting involved in other things.

Granny leads are “cheap” and built on a budget, their use should not be encouraged. The manufacturers of them aren’t going to spec them up as they will not be competitively priced.

Granny leads are okay if:

• The earthing system is TT.
• The earth earthing system is TNS.
• The earthing system is TN-C-S and the vehicle is being charged indoors.

The issue is when the vehicle is charged outdoors and the earthing system is TN-C-S, the answer to the issue is probably that Granny Leads should come with a health warning.
