Trumpy, I'm a city boy and I'm not familiar with milking equipment. But even if the suction cups are rubber, the cow is still electrically connected to the milking machine via the milk. Milk conducts don't it ?
I got a reply from the Energy Safety Service on this and they said that the Inspector was right. But could not point to any legislation that confirmed this. They're getting back to me on it.
I'm beginning to think that this is a situation which isn't covered by regulations, and maybe it should be.
