Description of ElectriCalc Pro Calculations:
• Work directly in and convert between Amps, Watts, Volts, Volt-Amps, kVA, kW, PF% and EFF%, and DC Resistance 
• Calculate wire sizes per NEC® 310-16 and 310-17; Copper or aluminum, 3Ø/1Ø, 60°C, 75°C, 90°C insulation ratings and 100% or 125% of ampacity. Can also adjust wire sizes for ambient temperatures other than 30◦ C and more than three wires in a raceway 
• Integrated voltage drop solutions. Find minimum VD wire size, maximum length for any given wire size, drop percentage, actual number and percentage of Volts dropped 
• Conduit sizing for 12 types of conduit. Per 2005 and 2008 NEC® Table C1-C12, find the sizing of all common conduits for any combination for #THW, #XHHW, and # THHN wires. 
• Find Motor Full-Load Amps per current NEC®. Works in 1Ø and 3Ø with the newly expanded tables for 3Ø induction (to 500 hp), synchronous (to 200 hp), and DC motors per NEC® 430-247, 430- 248 and 430-250
• Calculates Fuse and Breaker Sizes. Solves fuse and breaker sizes per NEC® 430-52 
• Parallel and derated wire sizing 
• Parallel Resistance 
• NEC Table number displays when performing Wire Size calculations 
• Sizes overload protection per NEC® 430-32 
• Automatically finds NEMA starter sizes
• Calculates service and equipment grounding conductor sizes per NEC®: 250-122 and 250-66; plus works directly in electrical terms. 
• Enter BTU to find Kilowatts per Hour
• Enter Kilowatts per Hour to find BTU
• Ohm’s Law Calculations – enter any two values to solve for the third
• Enter, solve, or convert to Circular MILS wire sizes

In addition to built-in help, the ElectriCalc Pro electrical code calculator is fully compliant with 2023, 2020, 2017, 2014, 2011, 2008, 2005, 2002, 1999, and 1996 NEC®.

Note: Electrical math is universal. However, code-based sizing solutions are based on the US National Electrical Code® (NEC); users in other countries should check with their local Code Officials for applicability.

Ratings and reviews

Better than the physical calculator. Only wish is that it would list the voltage entered on the screen. I spend a lot of time double checking my voltages. It would be great to see amps, voltages, distances on the display. Other voltage drop calculators have this option. With that said, this is still the best calculator in the app store.

Since I'm old & retired from electronics & electrical work, it's a useful help and more reliable than what passes for my memory these days. I do wish this company revived their old statistical process control and quality assurance calculator again. That would be useful as well.

Great app. Works just like the dedicated calculator. Have had no problems with it.
