10 Mobile Apps for Electricians and Electrical Contractors
The advent of mobile devices has provided unlimited access to tools and information available to electricians and electrical contractors. Along with this access comes the availability of applications (or apps) that can be downloaded on these devices that provide them with the tools that help make their jobs more productive.
There are hundreds of free and paid electrician apps out there for all types of electricians to use and they have a wide variety of functionality. LED Lighting Supply has put together a list of the best electrician apps and electrical contractor apps to help people of all skill levels. Our list includes apps that can help with simple tasks such as bending conduit to more complex tasks like NEC code calculations. They are available on iOS and/or Android devices.
Best Electrical Apps: Free & Paid
Electrical Calc USA
E-Calc is a mobile app that is a great on-the-job tool for electricians. It allows you to calculate typical electrical issues and return code results on your smartphone. Code results are based on the NEC, and they include conduit sizing, overload size, wire sizing, ground & bond size, fusing, and more.
Notable Features: Single motor calculations, transformer size calculations, panel legend creation, box fill calculations, allowable ampacity calculations, pipe size calculations, voltage drop calculations, Ohm’s Law calculations, common unit conversions, NEMA code finder.
Free version? Yes. A premium version is also available.
Electrician Calculator Pro
Electrician Calculator Pro allows you to easily perform NEC-compliant calculations on your mobile device. There is no need for the complex key combinations that your standard NEC calculator usually has. Because of this, it can be used by a wide variety of users which include electricians, maintenance workers, designers, inspectors, lighting experts, engineers, builders, and more.
Notable Features: NEC-compliant and includes free updates, voltage drop calculations, ampacity calculations, conduit sizing and fill, motor full load current value search, power cost estimates.
Free version? No
Southwire® Voltage Drop Calc
You can use the Southwire Voltage Drop Calculator to determine the best wire size for an electrical circuit. Its calculations are based on the circuit’s voltage drop and current carrying capacity. Wire size is calculated for a specific conductor run or to meet specific voltage drop limits. This app is designed for applications that use KCMIL and AWG sizes only.
Notable Features: Calculations automatically limit the wire size to voltage drop and NEC ampacity when sizing conductors.
Free version? Yes
Southwire® Conduit Fill Calculator
The Southwire Conduit Fill Calculator app is designed to calculate the conduit size that you’ll need according to the NEC. This includes jam probability and fill percentages. It has an intuitive interface that makes it easy to navigate. It’s quite handy if you don’t want to waste time with manual calculations.
Notable Features: Automatic calculation of conduit fill percentage per NEC guidelines, one-click results email generation, replaces NEC guidelines book.
Free version? Yes
Electrical Calc Elite NEC Code Calculator
Use the Electrical Calc Elite NEC Code Calculator to easily work out common electrical calculations in line with National Electric Code compliance. It will help electrical professionals solve NEC-related issues by accessing common NEC tables.
Notable Features: Available calculations include: conduit sizing, wire sizing, Ohm’s Law, fuse breaker sizes, voltage drop on wires, motor full-load amps, electrical unit conversion, Kirchhoff’s Law, parallel resistance, NEMA starter size, and more.
Free version? No
Master Electrician Reference
The Master Electrician Reference app is a handy guide for anyone doing electrical-related work in all sectors of the industry. You can replace hard copy reference guides by having access to them on mobile devices. You can also use it to perform helpful calculations.
Notable Features: Available references include distribution wiring diagrams, electrical formulas, capacitor and resistor color codes, kVA transformer ratings, wiring methods, NEC tables, electrical dictionary terms, ampacities, grounding sizes, and more.
Free version? No
PullCalc
The PullCalc app helps you to determine the estimated pull force that you need to install electrical cable inside conduit. Simply enter the requested information for each leg (a straight run of conduit followed by a bend) and then view the result.
Notable Features: Easy to use interface, connects to Bluetooth with your Smart Puller, record and data review, saves calculations and pull information, real-time monitoring of pull force, speed, and distance.
Free version? Yes
QuickBend: Conduit Bending Calculator
QuickBend is a conduit bending calculator that was designed to be fast, accurate, and easy to use. It produces accurate measurements by using the centerline radius algorithm that is based on the bender that you are using. You can choose between different types of benders and select the size of the shoe and conduit type that you’re using. You can also use the Bender Specs section to view and edit the information for the bender that you have.
Notable Features: Types of bends supported: three- and four-point saddles, offset, parallel offset, rolling offset, matching centers offset, matching bends offset, 90, kick w/ 90, parallel kick, multiple parallel kicks, matching center kick, matching bend kick, segmented 90, compound 90 – square obstruction, compound 90 – circle obstruction, compound 90 – rectangle obstruction.
Free version? Yes. A premium version is also available.
Electrician’s Helper
The Electrician’s Helper app makes it easy to perform estimates and calculations for installation jobs. You can also use it to look up electrical codes. Overall, it’s a very useful reference guide for electricians.
Notable Features: calculate Ohm’s Law, NEC table lookup, estimate maximum pull tension, calculate voltage drop, find total box fill, find ampacity of a conductor, determine raceway size for conductor bundles, find maximum conduit bend radius, convert temperature scales, and more.
Free version? No
Light Meter
Your iPhone or iPad becomes a light meter with this handy app. It acts as a lumen or lux meter and is much more affordable than other light meter devices.
Notable Features: Quickly determine lux and foot candle measurements, calibrated with a high-precision illuminometer, intuitive user interface (easy to use).
Free version? No
