Selection of multi-pin connector for power lead cables

Selection of multi-pin connector for power lead cables

Selection of multi-pin connector for power lead cables

(OP)
Hi,
I have 6 cables. Each cable has 3 wires: zero, phase, earth.
Each cable supplies 320W 230VAC heater (I have 6 heaters).

I am looking for 1 multi pin connector for all these cables for quick plug in/out.
Link to example connectors:
https://www.aliexpress.com/cheap/cheap-multi-pin-c...

I wonder how many pins my connector must have. I have 18 wires in 6 cables (6xZero, 6xPhase, 6xEarth).
Does it mean that I need at least 18 pin connector or can I have the earth wires connected together?

Also I have calculated that each heater draws approx. 1.4A (320W, 230VAC). Therefore, when I multiply 1.4A by 6 heaters my amperage is 8.4A. Sellers state the amperage for the multi pin connector. I understand that this is maximum load that the connector can take?
In my case should I then look for minimum 10A connector?

Please help.
Regards

Are the heaters controlled independently, or do they switch on and off together? If they are all switched together, use a terminal box to gather the connections and bring a single 3-pole supply in using, for example, an IEC320-type plug and socket.

@ScottyUK
Thank you for your answer.
The heaters are controlled separately through the PLC. Each heater requires separate wires.

Amy, you now have three separate threads going all about connectors for the same project. It makes sense to keep them all bundled up into one thread...
