How to Use This Calculator
- Enter the number of servers per rack and power draw per server.
- Set PDU redundancy (A+B feeds) and UPS design margin.
- Review kW per rack, required PDU amperage, and circuit breaker size.
- Flag racks exceeding 10 kW/rack for supplemental cooling (in-row or rear-door).
- Use the amperage output to specify PDU ratings and branch circuit protection.
