Hi guys,

With the formula kVA = I V for 1 phase, would the V be 120 or 240? Thank you all for reading.

Hi I apologize guys,

I have another question, but I don't want to clutter the forum. If there was a voltage drop of 20V on a 3ph line of 347/600, is the voltage at the service 327V or 580V, or both? Thanks you for reading.

??? Why would you say that? We don't know what he is using...

Hi Bob,

How can I know when to pick the line to line or line to n?

Update: I guess it can be chosen by if we want the max or not?

Methinks you are not an electrician...

If you are, you need to go back to basics.

I am not an electrician, but I work with them, and I realized through experience you guys know the answers to most things obvious and not. So I thought I could get some help on this.

the kva applies to the equipment that it applies to. In other words, a piece of equip using 240v x N amps would be using 240*N va. if the equip was using 120, it would be 120 x N va. it's that simple.

what are you trying to understand about voltage drop (can you phrase the question so what it is you don't understand is obvious ?)
