recommendedCrossSection now satisfies two criteria and takes whichever
demands more copper: the voltage-drop budget, and an ampacity at least
as high as the fuse protecting the circuit (ABYC E-11: the OCP rating
must not exceed the conductor's ampacity). Ampacity comes from ABYC
E-11 Table 6A for AWG and ISO 13297 Table A1 for mm², both 105 °C.
Before this, a 40 A load over 0.5 m was sized 1.5 mm² / AWG 16 next to
a 50 A fuse: a cable the fuse can never protect. Long runs stay
voltage-drop driven and unchanged.
The drop budget is now stored per system (3 / 5 / 10 %) and editable in
the system editor, with a global default in Settings that the
standalone calculator uses and new systems inherit.
Cross-sections are derived, never entered by the user, so LoadCableSync
re-derives them when a system opens and when its budget changes.
Library loads are computed instead of being stored as a 1.0 mm²
placeholder. LoadConfigurationStatus therefore reports only what the
user can actually fix: missing length or current.
Also removes the dead cable.pro.* strings and folds three copies of the
mm²-to-AWG conversion into ElectricalCalculations.nearestAWG.
- Fix AWG 0/00/000/0000 bug (all resolved to 0 in Swift) using negative
int convention (-1 through -4) with formatAWG() for 1/0–4/0 display
- Add 7.5A fuse size and change fuse type from Int to Double
- Add alternator power source type with distinct bolt.car.fill icon
- Migrate all NSLocalizedString calls to String(localized:defaultValue:)
- Update translations for runtime subtitle (ES/FR/NL: current→maximum),
usable capacity footer text, and NL override wording
- Store length always in meters, convert at display time in CalculatorView
- Add preview-friendly inits for ComponentLibraryView and LoadsView
- Expand test coverage for calculations, fuses, AWG, and edge cases
