Contactor Wiring

[Dru]

I am in the middle of a debate as to how to connect this contactor in the attached picture.

The live feeds are going from the breakers to number 2 in each contactor (1L1 to number 2 in the first contactor, 1L2 to number 2 in the second contactor etc) and there is a neutral from the neutral bar in the board to A2 in the first contactor which is then linked to A2 in the other contactors.

Which terminals would the outgoing live and neutral cables go in to for each contactor?

Simple as that.

Please can somebody put and end to this. The person I am debating with is severely annoying as he is adamant he knows how to connect it and will not have it when I am telling him he is wrong.

Thanks

looks like you have one of those annoying eye-phones that take a poor photo, then screw it sideways, so nobody but a giraffe can get their neck round far enough to see what it's about.

You do not say how you want to use them but assuming you want to switch both line and neutral then it is wired as a contactor really!
I would tend to feed the top but that is just me, normally easier to feed the lower terminals.
They are double pole contactors, and switch the load with a control circuit.

The individual neutral needs to be the same csa as the live, then you have a proper circuit.
Whoever is to test this for you will need a neutral on the earth bar for each feed to show on the test sheet (and a cpc each).

I've had a couple of beers so take this with a pinch of salt lol....

but I would say outgoing live 1, outgoing neutral 3???...

but as I say it's been a long hot day and I am 'relaxing' not necessarily thinking!

Trainee here with basic contactor knowledge but wanting to take a shot - going by Richard's diagram and your feeding from the bottom I'm going with:

Live in 2, Neutral in 4
Live out 1, Neutral out 3
Control in A2 , control (neutral) out A1?

If this is right would I be right in saying his neutrals could be linked on the outward side? Ie. A1 of each contactor (depending on RCD's etc?).

He already has control neutrals in A2 so the control line would be A1

Okay but ideally, would you place your control in's on the same side as your feeds?

And if only the live is to be switched then the outgoing neutral would go where?

 

[Richard Burns]

To the load!

 

[Dru]

Somebody just say straight into the neutral bar in the board so the fool will end this, it's ridiculous.

Why not? either way would be OK, I think. Normally your supplies would be coming from the same direction so it may be easiest to keep with the same side?

You do not currently have an incoming neutral (which would come from the neutral bar) why would you connect an outgoing neutral to the neutral bar? an outgoing neutral will go to the load.

 

[Dru]

I mean if you do not want to use the contactor as a double pole switch and just want to switch the live (as it has come pre wired with no neutral in 3) then you would take the neutral, for say circuit 1L3, straight from the neutral bar in the board to the load

Yes.....
