Thanks @333rocky333. I know what you mean by the small terminal on the metal wall box but this box doesn't have one. Hence I terminated it into a terminal block. Does that mean that my screws are currently live and hence dangerous?
I can drill a hole in the wall plate and find a way of connecting the earth wire there if that is a must.
