PhasePro

You spoke and we listened! Our app now includes 3 free tools, instead of just one! Enjoy full access to the phase colour tool, the wire ampacity tool, and the advanced notes/materials tool.

PhasePro brings practical electrical calculation and planning tools together in
a clean, jobsite-friendly app.

The free 3-Phase Calculator provides configurable phase colours, circuit lookup,
a visual panel chart, and shared-neutral phase-compatibility screening.

PhasePro Pro adds:

- conduit-fill calculations with common Canadian sizes and custom dimensions;
- voltage-drop calculations for single-phase and three-phase systems;
- box-fill calculations with common box-volume presets;
- equipment bonding-conductor lookup;
- conductor ampacity lookup with correction factors and small-conductor limits;
- panel load entry, phase totals, imbalance display, and balancing suggestions;
- panel-directory photo recognition with user review; and
- field notes, material order lists, quick selections, and associated-material
suggestions.

Choose light, dark, or system appearance and configure the app's default phase
colours and phase sequence.

PhasePro is an independent calculation and planning aid intended for qualified
electrical workers. Always verify results against the applicable electrical
code, local amendments, approved equipment instructions, field conditions, and
the authority having jurisdiction.
