The overload strength is an overload of the outputs (consumers use more than nominal current). Overload strength is defined generally for all interfaces. Furthermore, depart from this specification the overload strength can be defined for each connection regarding the description of interfaces.
The description of the overload strength is valid for all electrical connections (there is no reference to any electrical connection). If there are different descriptions for some electrical connections, a further description of the overload strength is defined for each difference (with reference to the concerned connection).
The MSR group defined the following description of the overload strength:

In addition to the a.m. statements there can always be given additional specifications, e.g. the test set-up.
