Panel Layout & Wire Colours
Enter circuit numbers for a standard panel and see the phase colour for each, plus a total wire count with optional shared (Edison) neutrals.
Standard panel layout: odd circuits on the left, even on the right, phases rotate every row.
Comma or space separated. Ranges like 1-6 are supported.
Groups of 3 circuits on A/B/C share one neutral.
