This scenario is usually by‐the‐circuit. Capacity should be determined using the PDU or remote
power panel (RPP) output breaker size for each primary (non‐redundant) circuit.
2. Output breakers can only be loaded to 80% of rating. Thus, a 20amp breaker provides 16amps of
power.
3. For single phase circuits, multiply voltage x amps x .8 to determine watts
For three phase circuits, multiply voltage x amps x 1.732 x .8 to determine watt
