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

• 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.
