## What is Wireman?

Size wire, check voltage drop and calculate conduit or box fill with nine free electrical calculators. Wireman brings everyday job-site tools and selected searchable NEC 2023 tables and summaries to your iPhone, even when you are offline.

See your inputs, results and calculation steps, with relevant references where applicable. Built for electricians, apprentices and maintenance technicians who want a clear record of their work.

NINE FREE CALCULATORS
• Wire sizing with temperature, bundling and terminal limits
• Circuit sizing: load, breaker, conductor and equipment ground
• Voltage drop and wire sizing for a target drop
• Conduit fill for THHN conductors in EMT, PVC Schedule 40 and RMC
• Conduit bending: offsets, three-bend saddles and stub-ups
• Box fill
• Single- and three-phase power
• Ohm’s law
• Unit conversions

NEC 2023 REFERENCE — INCLUDED FREE
Search selected tables and article summaries by number or topic, then open a related calculator. Contextual input help explains important assumptions. This is a practical reference, not the complete NEC text; the supported calculation baseline is NEC 2023. Other editions and local amendments are not modeled.

SAVE THE WORK WITH WIREMAN PRO
A one-time in-app purchase unlocks:
• Named jobs with customer details and notes
• Saved calculations with their inputs, results and workings
• Reopening, editing and duplicating saved calculations
• PDF reports for selected calculations, generated offline
• Text sharing and remembered conductor defaults
• Six additional calculators: Motor Circuit, Transformer, Fault Current, Dwelling Load, EV Charger and Grounding

Transformer estimates full-load current and primary-only fused protection for supported inputs up to 1,000 V. Fault Current uses an infinite-primary estimate; Dwelling Load uses a limited 240 V standard-method model. Check the assumptions shown in each tool.

Explore six read-only Pro examples and a sample PDF report before buying. Existing Pro purchasers receive the new Pro features at no additional charge.

No subscription. No ads. No account required. Calculators and reference tools work offline; buying or restoring Pro requires internet access. The App Store shows your local price before purchase.

YOUR JOB RECORDS STAY ON YOUR DEVICE
Jobs do not sync to an account. Export important records before deleting the app or its data. PDF and text exports are reports, not restorable backups. Older saved records remain readable and exportable; records without saved inputs cannot be reopened for editing.

Usage analytics is optional and off until you opt in. Calculator inputs and saved job records stay on your device unless you choose to share them.

Wireman is a reference tool, not a substitute for professional judgment or the adopted electrical code. Results depend on your inputs and each calculator’s stated scope. Verify against the applicable code and local amendments before performing work.

## Version history (last 2 releases)

### 1.1 — 2026-09-28

Keep the calculation and the job together.

NEW WITH WIREMAN PRO
• Organize calculations into named jobs with customer details and notes.
• Reopen saved inputs, edit an existing calculation or duplicate it for another circuit.
• Export selected calculations as PDF reports with inputs, workings, references and notes.

NEW FOR EVERYONE
• Explore worked previews of all six Pro calculators before upgrading.
• Get contextual help for important input assumptions.
• Preview a sample PDF report at no cost.

Decimal fields now accept a comma or a dot. The app stays in portrait, Settings labels are consistent, input help sits below its controls, and Rate Wireman opens the App Store review page.

This update also corrects two ampacity values, strengthens input validation and improves storage-failure handling. A visible editing banner and New calculation action help keep saved-record edits separate from fresh calculations. Large conductors use the correct kcmil label in saved records and reports.

Existing Pro purchasers get the new Pro features at no additional charge. Existing saved records remain available; older records without saved inputs remain readable and exportable.

### 1.0 — 2026-08-12

No release notes.
