What's New in GUIOMAR Field Tools Parallel Conductors — Wire Size Calculator High-amperage loads often require parallel runs. The Wire Size Calculator now lets you select 1, 2, or 3 conductors per phase before calculating. The app divides your load accordingly, finds the minimum wire size per conductor from OESC Tables 2 & 4, and displays the total ampacity of the parallel set — per Rule 12-108. Example: 800A load @ 75°C Cu 1 conductor → Exceeds table range 2 conductors → 2 × 600 kcmil Cu (420A each / 840A total) 3 conductors → 3 × 300 kcmil Cu (320A each / 960A total) Built by an electrician, for electricians.
