Allocating half of the VA to each line is normal. And then after adding up all loads you use the 3 phase power equation to get the line current.If it's line to line, it does not split. The entire 8320 Watts flows on both legs.
well it couldn't be 8320 Watts on both phase A and B right? that would be 16.64KW. So is it 8320W from phase A and 0 from phase B?If it's line to line, it does not split. The entire 8320 Watts flows on both legs.
can we assume it is perfectly balanced for now? I am just trying to get a better understanding for how it works.Can't say for certain. With a neutral involved, it could be unbalanced.
^ what infinity said.well it couldn't be 8320 Watts on both phase A and B right? that would be 16.64KW. So is it 8320W from phase A and 0 from phase B?
If you add all three line totals, and the result is the average line current. Use single phase power formula on each individual line total to get approximated individual line current.Allocating half of the VA to each line is normal. And then after adding up all loads you use the 3 phase power equation to get the line current.

If you are doing this like a panel, adding up volt-amperes (VA; watts ÷ power factor) per line (A, B, C), then you use half the load VA per line.can we assume it is perfectly balanced for now? I am just trying to get a better understanding for how it works.
Thank you
I think this may help you out and answer your question without getting over complicated. I think you are asking for a panel schedule as Smart suggested so refer to his answer, but here is a picture of a panel schedule of mine.View attachment 14747
Refer to pic. I have a line to line load of 8320 Watts on a 120/208VAC panel 3phase as shown.
does the power split evenly between the 2 phases? so 4160W is taken from phase A and 4160W from phase B?
thank you
thanks for the explanation. Although I'm surprised your calculated load is higher than your connected load. Isn't calculated load basically your demand load?I think this may help you out and answer your question without getting over complicated.

Take the "Rotary Cup Filler" in space 8,10,12 for example. The load for this piece of equipment is 16.63 KVA. You'll see the load split between A,B and C to the right at 5.54 each. Hope this helps!
Connected load is what is physically connected. Calculated load may have demand factors applied to it or portions of it.thanks for the explanation. Although I'm surprised your calculated load is higher than your connected load. Isn't calculated load basically your demand load?
There are also minimums to calculated load, such as lighting per square foot calculating out to more than the connected load.thanks for the explanation. Although I'm surprised your calculated load is higher than your connected load. Isn't calculated load basically your demand load?
