Engineering Reference
DC Hub Technical Manuals
Super-detailed methodology for every calculator, cockpit, lab and tracker on the DC Solutions hub — the inputs, the exact formulas and where they live in the engine, the sourced constants, the output equations, an engine-verified worked example, and the governing standards. Each manual is the audit trail behind a live tool.

How to read a manual. Each page follows the same eight blocks: purpose & basis · inputs · calculation methodology (every formula, with the engine function it lives in) · constants & data sources · outputs · a worked example verified against the live engine · references & standards · assumptions & limitations. Where a page uses live published data (PLN grids) or editorial ranges (comparisons), the manual documents the basis honestly rather than presenting invented equations. These manuals are engineering education and pre-design aids — final design must be sealed by a qualified engineer to the authority having jurisdiction.
