I am an electrical engineer who has to learn all those norms. The normal eueopean "Schuko" plug is rated for 16A short term and 10A long term. Long in that context means everything above 1 hour of continous load, which should cover typical applications of water cookers. The wall sockets are typically the same, although 16A continous variants exist and old wall sockets with bad contacts can easily heat up enough that I would avoid ever going over 10A with them if it can be avoided.
