Alex raised an eyebrow. "That's pretty thick. Are you sure you need that much?"
For critical infrastructure projects, cable sizing should not be a generic schedule item but a distinct engineering deliverable, complete with thermal studies and loss analysis, to ensure system resilience and long-term profitability. cable size
In the electrical world, is king. The lower the gauge number, the thicker the cable. Alex raised an eyebrow
Note: Aluminum wire (common for service entrances) needs to be 1-2 sizes LARGER than copper to carry the same load. In the electrical world, is king

Mike nodded. "Good. Make sure you double-check your calculations. We can't afford any mistakes on this project."
