I have to supply a 3 phase + neutral circuit but I have to run it through a contactor. The contactor is 3 phase no neutral and will be bushed onto the left side of the board with 2 bushes (one for feed, one for load).
The other side of the board is bushed onto some trunking where the load will go out of.
Am I right in thinking that I can just take the 3 phases no neutral in and out of the contactor trough the separate bushes, and take the neutral from the load straight into the DB busbar and not run it through the contactor? So the outgoing load with 3 phase & neutral all go through the same bush, but the cables in and out of the contactor that don’t require a neutral don’t need a neutral through the same hole?
Apologies if this isn’t explained well enough it’s hard to put into words without a drawing.
