Calculate power feed requirement

[BillP]

Hi guys,

Would somebody please be able to help me with this question.

I have 2x 5000VA (22A) units and 1x 3000VA (10A) unit. Each unit is loaded in this way 1) 5000VA - 2150W 2) 5000VA - 2140W 3) 3000A - 1550W
Considering that the max W output per unit is 3750W for 5000VA unit and 2700W for 3000VA unit, the average load per unit is about 57%

The question: I have one 32A (240V) single phase line, will it handle all those 3 UPSes?

Thanks for your help.

in general it will not handle you have to take in consideration the over load an peak current .
in most time the peak current can go to 3 times for the real current, this men you can face a peak current sized to 42 amps at minimum, but this depend in your load
specification,if it is resistive load the line wil handle, else if you have pc and servers or printers ( lazer printers), you will face problem with the line.
