About Ugly's Electrical References
The Ugly's Electrical References App has been updated to reflect changes to the 2023 National Electrical Code (NEC) and the 2023 Edition of our popular Ugly’s Electrical References book. The Ugly’s App offers the most pertinent, up-to-date digital information for electricians, including table change information, mathematical formulas; National Electrical Manufacturers Association (NEMA) wiring configurations; a conduit bending guide with videos, ampacity and conduit fill information, transformer and control circuit wiring diagrams, and conversion tables. The 2023 Edition: * Reflects changes to the 2023 NEC * Features expanded coverage of the following topics: * Full-load currents for 3-phase transformers * Maximum number of conductors in electrical metallic tubing for trade sizes 5 and 6 * Equipment grounding conductors * General lighting loads for non-dwelling occupancies * Overview of important NEC code changes from 2014, 2017, 2020, and 2023 Electricians and electrical professionals have used ‘Ugly’s Electrical References’ book as their on-the-job reference for over 35 years. This app will serve you even better in the field today. FEATURING Calculators and Interactive Features *Ohm’s Law Calculator *Voltage Drop *Ampacity Calculator *To Find: Amps, Watts, Horsepower, KVA *To Find: Inductance, Impedance, Reactance *Three-phase AC Motor Data: Starter, Breaker, Heater, Wire, and Conduit Size *Power Factor Correction *Full Load Current for Motors and Transformers *Locked-Rotor Current Calculator *Offset Bending Calculator *Conduit Fill Calculator *Conversions for Area, Length, Temperature, Time, Volume, and Weight *NEMA Wiring Configurations **Pinch & Zoom for improved readability **Video Tutorials of Conduit Bending **Search function helps you quickly find what you need to know **NEC Updater outlines and explains changes to the National Electrical Code© **Electrical Safety including definitions, boundaries, procedures, PPE guidance and life-saving first aid procedures **Blueprint symbol identifier **Bookmark your commonly used screens **High-definition images and interactive tables that can be zoomed in for detail **Works when you are offline and out of range **Great for electricians, students, engineers, contractors, maintenance workers, and military ********************************************* Interested in a buying more than one copy of the Ugly’s Electrical Reference app for your commercially owned devices?

What Ugly's Electrical References Is Used For
Ugly's Electrical References appears to be a field reference and calculation app for electricians and other electrical professionals. Based on the metadata, it is designed to provide quick access to NEC-related reference material, wiring information, formulas, conversion tables, and practical calculation tools that can be useful during installation, troubleshooting, and code lookup tasks.
The app also seems built for jobsite use on a phone, with features like search, bookmarks, zoomable tables and images, and offline access. That makes it suitable for situations where a user may need to check ampacity, conduit fill, motor data, transformer values, or NEMA wiring configurations without depending on a constant internet connection. The permissions listed, such as storage access and network access, may support content loading, updates, and saving user-selected reference items. It also includes video tutorials and safety-related reference sections, which suggests it is meant as a practical companion for day-to-day electrical work rather than a general-purpose productivity app.
