I just picked up a new Jayco today and picked up a 15 amp power lead. Forgot that the male plug to connect to 240 v would also be a 15 amp plug with the larger earth pin, therefore wont fit! On my previous van (bought off my parents 10 yrs ago) it too had a 15 amp plug but the male plug was a 10 amp pin set. ( I think dad changed it himself) What have other people done to deal with this situation which is safe and 'legal' (not interested in grinding pin down!) thanks
