9kW 3ph Immersion Type Heater run in Single Phase

[Pete999]

Hi Pete,My friend sent me this. I still didn’t manage to re run this thing. Please recommend wire sizes and if 3ph to single phase conversion was made, what will be my effective current requirements? Will a 25kva transformer be enough?
Again its a 230V 9kW 3ph immersions heater originally. My friend from india said that it requires around 63A if current when it was at its 3phase form.

Can't offer "how to" advice From a distance Jon, not knowing your Skill set, best call a local electrician in your location.

If you are running all 3 elements on the same phase, be aware the neutral current will be the sum of all the loads.

Jon with all due respects to your Friend in India, The diagram you linked is just a diagram of how a 3 phase Star connected load is connected, and how the N amd E are derived from this system, your post leads me to believe you don't trust your Friends' judgment of the situation, asking for a second opinion on an internet Forum is not good advice in this situation, like I said earlier you need to contact someone local to you, for help and guidance. That is the best advice I can give you.
