If the parallel or series connections are made directly at the connecting bars, for thermal reasons the continuous load on the circuit breakers must only be 80 % of the permissible operational current. If the parallel or series connection is made at a distance of 1 m from the connecting bars, the circuit breaker can be used at full operational current load. ] Grounded-neutral system Load Siemens · 2012 57
