## NG Wire Description
NG Wire™ is a professional NEC® reference and calculation app for electrical engineers, electricians, designers, inspectors, and contractors. Quickly look up ampacity, grounding conductor sizes, minimum cover requirements, motor data, and perform conduit fill calculations.

Designed for speed, NG Wire™ delivers the information you need with just a few taps, eliminating the need to manually navigate multiple NEC® tables. Whether you're designing in the office or reviewing installations in the field, the app helps you find accurate information in seconds while reducing the chance of calculation or lookup errors. No more flipping through printed code books or searching PDF tables while on the job.

NG Wire™ includes 11 of the most commonly used NEC® tables and calculation tools:
     1.   Wire Ampacity
     2.   Ambient Temperature Correction Factors
     3.   More Than 3 Conductors in Conduit Adjustment Factors
     4.   Equipment Grounding Conductor (EGC) Sizing
     5.   Grounding Electrode Conductor (GEC) Sizing
     6.   Upsized Equipment Grounding Conductor (EGC) Sizing
     7.   Conduit Fill Tables
     8.   Conduit Fill Calculations
     9.   Minimum Cover Requirements
     10.   Single-Phase Motor Data
     11.   Three-Phase Motor Data

NG Wire™ requires either a monthly or annual subscription. Every new subscription begins with a free trial that includes full access to all app features. After the trial ends, subscriptions automatically renew unless canceled through your Apple account. You can manage or cancel your subscription at any time from the Settings menu in the app.

NG Wire™ includes data and calculations based on the 2026, 2023, and 2020 editions of the NEC®. Your subscription also includes future updates as new NEC® editions are released (typically every three years). Older NEC® editions will remain available as long as they are still adopted by one or more U.S. jurisdictions. Advance notice will be provided before any older edition is removed from the app.

### ***** "Using it every day!"
Wow! Great app. Thank you for making this. This lets me do daily circuit and feeder sizing, conduit, sizing and percent fill calcs for a bunch of different wire types, cover requirements, and motor values all in one place. No more codebook or lookup tables. Worth every penny when you consider design time. Really nice screen layouts too. Very intuitive.
