I can't see why it's so complicated, surely it's just a battery charger fixed to the wall? Well a bit more complicated, actually maybe not, it's a damn battery charger.

I don't see an earth rod next to my Duracell charger, or one that I plug in then put on the van battery?

Can someone explain who knows, why it is so involved.


its not the charging unit, its the car! when its plugged in, if you have a lost neutral on the incoming main then the car is a great big lump of live metal insulated from the ground, then if someone touches it whilst also touching a steel fence post in the garden etc etc.......u get the picture

also potential difference between earthing systems is also a problem

Whos ever been up a scissor lift and put their arm on the metal tray work and got a belt? I have!


I looked up 16a and 32a isolation transformers today for the electrical separation option.......not much change out of a grand! Class 2 external light fittings all round i think!
 
I was thinking about this today, and did think if it was because you could have a car isolated from the ground due to rubber tyres etc.

Makes sense nw looking at it like that, but still think its a bit over the top and needs reinventing.
