Please note, the easypact EXE can be fed from bottom or from top.
When the supply is being fed from the bottom - it will be called incomer feeder - the supply will go to the busbar and then distributed to other cubicles in the switchgear.
In short, the easypact EXE circuit breaker can be fed from bottom or from top. However, if using fixed type of circuit breaker and when connections are made on the circuit breaker for the top and bottom, care needs to be taken so as to ensure adequate clearances are maintained between the phases and between phase-earth while making connections to the circuit breaker. Also, adequate support needs to be given to the load connections at defined distances so that the circuit breaker is not experiencing abnormal load.
