Hi,



I would like to know the Kva for the following appliances.


4 freezers at 5 amps each


3 chiller units at 3 amps each


2 chillers at 35 amps each.

I do not know if they are resistive or conductive(if that is necessary for the answer)



Would the answer be 99 * 240 /1000 = 23.76??



Hope you can help.



Confused

It's not "conductive", it's "reactive", but if you're taking the ratings from the nameplates and you're running the appliances on 240V mains then, yes, it's 23.76 kVA,

Notice that John write kVA as opposed to your Kva...John is right so write the units that way.

The units should be written all upper case, KVA. The convention is that for units above unity, the prefix is caps; e.g., K for Kilo, M for Mega, etc. For units less than one, the convention is to use lower case; e.g., m for milli, u (mu) for micro, etc. Bob

You are correct, I screwed up. I don't know where I got that idea. Bob

Where did you get that information? Everything I see says that anything < 1E6 is lower case, while anything >= 1e6 is upper case.
