Each Division of the Counties Championships is run in two parts: the Union Qualifying Stages (within which each Union has autonomy) and the National Stages. Counties compete in the National Stages by virtue of qualifying from the Union Stages or otherwise being nominated by the Unions.
The Divisions are Open, U2050, U1850, U1650 and U1450. Under in this context means that all team members must be below the limit.
In the National Stages, there is also a separate Minor Counties Championship for counties which fail to qualify for the National Stages of the Open Division. Teams in the MCC must have an average rating below 2050.
The above is simplified slightly, but not much.
