Lineman Field Guide

The book in your bag, on your phone — with no signal.

A reference and field tool for electrical linemen, cablemen and apprentices. Minimum approach distance, sag and tension, transformer connections, conductors, knots, rigging and the OSHA text — all of it stored on the phone and readable in a hole with no bars.

Coming to Google Play. Android.

Built for the truck, not the office

Big targets, big numbers, and a screen that stays lit while you read it. Every calculator states the formula it used and where the numbers came from.

Minimum approach distance

MAD by voltage and altitude, with your employer's own adders if they differ from the federal table.

Sag & tension

71 conductors — ACSR, AAC, AAAC and copper, solid and stranded — with ruling span, ice and wind.

Transformer connections

Eighteen bank connections with the wiring steps, expected voltages and the cautions that matter.

Bank simulator

Wire a bank from bare pots, close the fuses, read the meter, get graded. Every connection in the reference is one you can practise.

Knots & rigging

Twenty knots illustrated from public-domain Army and Navy manuals, plus sling angles and load charts.

Job briefing

A template for working through the briefing OSHA 1910.269(c) requires, exportable as a PDF.

Height by angle or photo

Sight a wire along the top edge of the phone, or measure from a photo with something of known height in frame.

Storm work

Hours, per diem, miles and job, with the federal per-diem split — exports to CSV or PDF at the end of the roll.

Apprentice

OJT hours, certification reminders, quiz decks and job scenarios that score the decision, not the trivia.

On the phone

Everything below works with the radio off.

What it is not

This is a reference, not an authority. It does not replace your training, your employer's rules, the equipment nameplate, or a qualified person on site. Every page names the source it came from so you can check it. Nothing in it is a substitute for testing and grounding the line yourself.

Your data stays on your phone

No account. No sign-in. No tracking, no analytics SDK and no crash reporting. Job briefings, hours and notes are stored on the device and go nowhere unless you export them yourself. The only things that reach the network are the ones you tap: a weather lookup, the news feed, and the community study decks.
