Power Output Calculations

Based on the 2000-amp maximum switchgear capacity at various voltages:

• At 480V, 3-phase: 2000A × 480V × √3 × 0.8 PF = approximately 1,330 kW
• At 600V, 3-phase: 2000A × 600V × √3 × 0.8 PF = approximately 1,663 kW

Note: Calculations assume 0.8 power factor (typical for industrial generators). These are calculated maximum capacities based on the electrical distribution system. Actual generator nameplate rating should be verified from factory documentation for precise specifications.
