How to size a UPS

1. List all equipment to be protected by the UPS.
2. List the amps and volts for each device.
3. Multiply the VA by the number of pieces of equipment to get the VA subtotals.
4. Add the VA subtotals together.
5. Multiply the total by 1.2 to get the grand total.
6. Use the grand total to select a UPS.
