The Reference Library is ArcReady's set of quick-access tools — for when you need a formula, a symbol, or a code comparison mid-study without digging back through the full guide.
What's In It
| Tool | What It's For |
|---|---|
| Symbols Glossary | Standard schematic symbols for motor starter controls — contacts, coils, fuses, grounds. Also covered in the Glossary. |
| Ohm's Law Calculator | Interactive solver for voltage, current, resistance, and power — enter any two values, get the rest. |
| Formula Sheet | Every electrical formula used across the Theory question bank, printable for offline reference. |
| Standards Details | Side-by-side comparison of Workplace Standards vs. NFPA 70E framing. |
| PPE Categories | The four HRC / arc flash PPE categories (0–4), minimum arc ratings, and required gear — full detail in the Study Guide. |
| Approach Boundaries | Limited, Restricted, and Arc Flash Protection boundary distances and rules. |
| LOTOTO Procedure | The 8-step lockout/tagout/tryout sequence, in order. |
Study Resource Library
Beyond the quick-reference tools, the Reference tab also includes a downloadable/streamable library of study decks and guides (PDF and slide formats), filterable by topic, plus a guided study presentation that walks through Workplace Electrical Safety fundamentals, the Ohm's & Power Law masterclass, and a Virtual Lab walkthrough as a slide-style overlay.
Printable Cheat Sheets
Under Study Mode, you can toggle a Cheat Sheet view that compiles every question and full explanation into one printable page — useful for offline review or a physical copy on the jobsite.
Two more reference formats: the full write-up, and the short-definition version.
