NG Wire | NG Orange, NEC, NG Wire, Construction App

NG Wire™ is an app for professionals involved in the electrical construction industry. NG Wire™ utilizes popular National Electric Code® (NEC®) tables for general building wiring, conduit, and motor data. Users can look up values and handle general and detailed conduit fill calculations, based on these NEC® tables.

The app streamlines the daily process of wire, motor, and conduit calculations for fast, efficient, and accurate results. NG Wire™ can go with you anywhere, from your office as you design, to in the field as you review or plan an installation and need quick reference to NEC® data. Gone are the days of using cumbersome code book paper or PDF look-up tables.

NG Wire™

The app includes 11 of the most used NEC® tables and calculation topics. These include:

Wire Ampacity
Ambient Temperature Correction Factor
More Than 3 Current Carrying Conductors in Conduit Adjustment
Equipment Grounding Conductor
Grounding Electrode Conductor
Increased Size Ground Wire
Conduit Fill Tables
Percent Fill Calculations
Minimum Conduit Cover Requirements
1-Phase Motors
3-Phase Motors

Wire Ampacity

Ampacity is used to look up the rated ampacity of insulated conductors rated 0-2000V, installed in an ambient temperature of 30°C/86°F, with no more than 3 current carrying conductors in a raceway, cable, or earth (directly buried).

Ambient Temp is used to look up the ampacity temperature correction factor for conductors used in temperatures other than 30°C/86°F and 40°C/104°F.
More Than 3 is used to look up the ampacity adjustment factor to be applied when there are more than 3 current carrying conductors in a raceway or cable.

Grounding

Equipment is used to look up the required minimum size of an equipment grounding conductor used to ground raceways and equipment.
Electrode is used to look up the required minimum size of the grounding electrode conductor for alternating current systems.
Increased Size is used to calculate the required upsized equipment grounding conductor size for a branch circuit or feeder, where the ungrounded phase conductors have been increased in size to accommodate other parameters such as voltage drop.

Conduit Fill

Fill Tables is used to look up the maximum number of conductors of the same type and size that are permitted to be installed in one raceway.
% Fill Calculation is used to calculate the percentage of conduit fill for up to 4 different types and sizes of conductors installed in one conduit.

Minimum Cover

Minimum Cover is used to look up the minimum cover requirements for buried conduits or cables, from 0 to 1000 Volts.

Motors

1-Phase is used to look up the full load current values for different sizes of 1-phase motors.
3-Phase is used to look up the full load current values for different types and sizes of 3-phase motors.
