July 10, 2026 — Voltage-drop OCPD floor, grey outputs, remember config

Path: _pwa-build/ · July 10, 2026 (site v1.0.26) · SW cache v62

Bug: At high system V (e.g. 600 V), pure 3% drop sizing could recommend 14 AWG for a 20 A load at ~100 ft.
Fix: calculateVoltageDrop() starts at the CEC load/OCPD floor via lookupWireCu(amps, amps, '75') (20 A → min #12), then walks for drop ≤ 3%.
Status note when the floor applies: e.g. Min 12 AWG for load OCPD; drop OK @ N ft.
Still requires explicit load amps + one-way length; incomplete inputs clear sticky wire results.

localStorage key phvac-elec-prefs (JSON): region, VD voltage/phase/material, 3φ voltage, RLA/FLA, temps, other voltage selects.
Not stored: free-text load values (amps, length, RLA numbers, etc.).
CLR STEP / CLR ALL leave remembered config alone. Legacy phvac-elec-region kept in sync.

Calculated fields use read-only <output class="elec-out"> (grey slots); code notes use elec-out-note.
Compressor RLA/FLA toggle; est. inrush display-only; help covers VD floor + remembered settings.
