SINGLE PHASE PANEL BOARD TO THREE PHASE PANEL BOARD

[alvin.rvt]

Hi I just want to ask how to create single phase panel board, then how to connect it to three phase panel board.

Thanks A Lot

Hi,

I create for you some sketch. Firstly I think you can adjust the voltage settings. If not you have to check, Voltage Defination and Distribution Syste settings.

Than you can follow my route.

After that, you can connect your single phase panel to 3 Phase panel.

thanks for the help, i created this sketch that you give but my second problem is when i put some electrical fixture to my single phase db it create single phase load but in the three phase db in goes to phase R & phase Y,

How can i make it in three phase DB for same phase R?

if I understand it correctly. On the link below, my first message can help you. You can change your circuit number in the panel schedule.

yeah the first one is very helpyful, but in the three phase panel board you cannot make the same phase the load from single phase panel board.

for example I put a 3 electrical fixture to single phase db then when i connect the single phase db to three phase db the load is not in the same phase. as you can see in my attach file the other load goes to phase Y.

Yes, its normal. If you want to change phase, you can click Rebalance Loads. But it will effect all circuits.

Why you want to put same phase i don't understand.

"Why you want to put same phase i don't understand "

Because when you use single phase db is in one phase only, so when you put the single phase db to three phase the load of single phase db should in one phase only.

"Because when you use single phase db is in one phase only, so when you put the single phase db to three phase the load of single phase db should in one phase only."

It is True. 

"when you put the single phase db to three phase the load of single phase db should in one phase only"

Yes, my point, you want to change db phase in 3 phase schedule ? If yes you can use Load Rebalance but it will effect all circuit or you can just move circuit number in 3 phase schedule, as you want to put your phase column.

[alvin.rvt]

All i want is to use a single phase db connect it to three phase db, but the load in three phase db should be in one phase. Is that possible?

[GungorOzay]

Unfortunately you can't. If you want use all DB panel in one column (means phase) You have to connect single phase system. Otherwise you can not.

Hello,

You can create a single phase panel, but the panel part type setting must be switchboard.

Then you assing a single phase distribution system to it.
