It is worth spending a few quid on an adapter to fit the french 'standard' bollard, although many sites have introduced the euro points. Either way be sure to test polarity as the french use double pole switching ( both +ve and -ve disconnected) they have no polarity concerns, but as we have single pole (only the live disconnected) our appliances could still be live when switched off if polarity is reversed. Many caravanners make up a short adapter lead with the +ve and -ve deliberately swapped in one end. If you do this you MUST label the lead well to avoid any mistaken misuse.
