I have several devices in the same phase, hence the question about them being in series

Yes the source has a neutral. It is not an imaginary problem. I was thinking of connecting the devices in parallel across each phase so they each see the same voltage and draw whatever current they require. Here is a diagram, let me know what you think

The power supply provides 415V, all the individual devices take 240V. What I am having trouble understanding is when I connect the selected devices on the line to neutral(across each phase) in series, the current flowing through them is the same but voltage across each will be different. But I...

What is this point? Can you please elaborate?

There has been a few changes Ph1: 12.5,2.3,1.3 = 16.1A Ph2: 12.5,2,2 = 16.5A Ph3: 6.7,6.7,2 = 15.4A Current in neutral = 0.96A

Does this mean each of those devices will be connected in series to each of the phases (across line to neutral that is)? Neutral as common as in connect the loads in Y formation?

What should I do with the neutral connection? Does it have to be grounded?

Hi there, I want to know what is the best way to connect these devices to a 3 phase power supply outlet and minimise the unbalanced load as much as possible safely? I am only worried about the single phase appliances. What type of connection would you recommend? 3x Power Supply units Single...
