Materials catalog
Build a reusable list of your electrical materials. Tap Add to job to put an item on the job selected below. Your catalog stays intact.

How this works
A catalog item is a reusable material template. On hand in the catalog is optional shop stock, separate from the quantities assigned to a job. Adding a catalog item to a job does not subtract shop stock.

Field tools
Conduit bending
Pick the bender brand, style and model, then select the actual conduit and shoe. Save your shoe-chart values for next time.
1 · Choose your bender
Choose a model, or select Custom to enter your own.
2 · Enter your shoe-chart figures
Required for 90° stub. Use the value for the selected conduit and shoe.
Useful when recording your specific shoe.
Model listings identify actual bender products, but most chart values are intentionally blank until verified for your exact shoe. Manufacturer manuals should take priority over a generic calculation.
3 · Select a bend
Marking & layout
Check the specific model, shoe, conduit material and manufacturer manual. For hydraulic and mechanical benders, the machine may use centerline marks or ram-travel charts rather than a hand-bender arrow. The general offset spacing formula is not a manufacturer setup instruction.
Field tools
Electrical calculations
Fast field estimates with labeled inputs and transparent formulas.
Voltage drop estimate
Approximate K-factor method at ~75°C; AC reactance, installation conditions, power factor and terminal limits may alter results. Not a substitute for code verification.
Power / current
Single-phase: P = V × I × PF. Three-phase: P = √3 × VLL × I × PF. Assumes balanced three-phase load.
Field tools
Wire & unit conversions
AWG through kcmil, circular mils, and approximate metric cross-section.
Wire size
Area conversion only; not an ampacity calculator.

Interactive function check
If the app is running in a browser, tapping this button will test the sidebar, screen switching, bend selector, forms and calculators without changing your saved job data.
The test has not run. If the button does nothing, this viewer is blocking the app's JavaScript.
Export and restore
JSON preserves jobs, catalog, planned materials, tasks, links, photos, shoe profiles and activity history.
Restoring replaces everything currently stored in this app. Save a backup first.
