In at least one embodiment, a method includes setting a dedicated current limit value for the upstream switch; opening the upstream switch each time a current limit value thereof exceeds the set dedicated current limit for a set time; connecting the two switches to one another in terms of signaling; and signaling the upstream switch, via the downstream switch, each time the downstream switch is going to interrupt the current, at least one of the current limit value being increased and the set time of the upstream switch being extended each time the downstream switch signals that it is going to interrupt the current.
