FeederFlow

Quick start: + Add Run → name the line (e.g. Panel 1, Motor 1, LP11) → set breaker and route length → check Panel Schedule below for results. Use Copy (Dup) to repeat settings on a new line.

Status badges: Simple view is the default — each row shows a status badge and sizing summary. Auto re-runs NEC sizing (Table 310.16, 240.4, 215.2 VD, parallel layout) and raises Par as needed up to 20. Limit only appears when even 20 parallel sets cannot meet code at that length.

Auto sizing: Hot, neutral, ground, parallel sets, and conduit default to Auto. Manual picks stay locked until you choose Auto in that field or click the row Auto button. Override is for experienced users hand-editing every field.

Bundling: Off uses NEC Table 310.16 table ampacity only. Auto applies NEC 310.15(C)(1) current-carrying conductor adjustment when conductors are bundled in raceway.

View presets: Simple hides advanced columns. Standard is recommended for most jobs. Advanced shows every column. Turn Custom on and use the dropdown (▾) to pick individual columns.

Ground: Sized per NEC 250.122 and 250.66. Turn on Copper ground (Cu G) for pool, pump, and water-related equipment — copper equipment ground even when phase wire is aluminum.

Downsize neutral: The neutral is the NEC grounded conductor (not the equipment grounding conductor / ground wire). With parallel sets, neutrals run in parallel like hots — one per path in each raceway (NEC 215.2(B); 250.122(F) does not apply). On eligible feeders, check Downsize Neutral to reduce each parallel neutral one wire size per NEC 220.61. The 250.122 minimum is per parallel set (breaker ÷ Par), not the full breaker on every neutral. Not permitted on 1Ø 120/277.
