HERSHEY MEDICAL CENTER PRESENTATION OUTLINE � � � � Feed From Inverter to Combiner Panel/Box Sizing I. PROJECT BACKGROUND � Max current from inverter data sheet: 91A/phase II. INTRODUCTION OF ANALYSIS 15kV Utility In DC Power From Array � 91A x 1.56 (NEC Multiplier) = 142A III. ANALYSIS #1: FOUNDATION RE-DESIGN I. Initial Conditions � NEC Table 310.15(B)(2)(a): Multiplier for 4-6 current carrying 500 kVA Transformer 500 kVA II. Re-Design conductors in a raceway = 0.8 Satcon 75kW Transformer Inverter IV. ANALYSIS #2: ROOFING � NEC Table 310.16 (90°C Wire): 2/0 AWG = 195A I. Part I: Roofing Type Comparison Inverter 1 set of (4) 2/0 AWG Main Electrical Room Net Meter 195A x 0.8 = 156A > 142A => OK II. Part II: Elimination of Offset Roof Production Meter Combiner V. ANALYSIS #3: RENEWABLE ENERGY AC FUSED DISCONNECT SWITCH SIZING Panel/Box I. Part I: Geothermal System � Max current from inverter data sheet: 91A/phase Load Meter 400A AC Fused II. Part II: Installation of PV Array Disconnect Switch I. Site Analysis � 91A x 3 phases 1.25 (NEC Multiplier) = 342A II. System Design Main Distribution Panel � Ideal fused disconnect switch size: 350A => not available => 400A VI. SUMMARY & CONCLUSION VII. ACKNOWLEDGEMENTS � Interrupt Rating must be greater than; 500kVA / (.480kV * 3^ (1/2) = 600A
