This electrical riser diagram maps the connections between a new inverter ELC and associated transformers and panels. The system incorporates new 30 kVA 480V to 120/208V transformers T-LC2 and T-LC4 alongside existing panels HLC2 and LLC4 and new panel LLC2. Conduit and wire sizing are specified for each run, including 2-inch conduit with four 1/0 conductors and one number 4 ground for the 210-foot run to panel HLC2, and 3/4-inch conduit with three number 8 conductors and one number 4 ground for the 10-foot run. Additional connections utilize 1 1/4-inch conduit with four number 2 conductors and one number 6 ground for existing panel LLC4.
