The standard is the round 16 A two pin plug with the ground pin in the socket. (Two pins on the plug and one in the socket).
I can only think of one blue circular power plug that supports two 2 x 10 amps: A 32 A CEE plug combined with two fuses in your equipment. Or supply two 16A cords with plugs...
Another solution is to check if all parts of the equipment need power at the same time. If not, maybe you can do with 16A.
