Description of Calculations
• Convert between Amps, Watts, Volts, VA, kVA, kW, PF%, Efficiency%, and DC Resistance.
• Ohm's Law Calculations: enter any two values (ohms, volts, or amps) to solve for the third.
• Calculate required wire size per NEC® tables 310-16 and 310-17; Copper or Aluminum, 3ø or 1ø, 60°C, 75°C, 90°C insulation ratings and 100% or 125% of ampacity. Adjust wire sizes for ambient temperatures other than 30°C and for more than three wires in a raceway.
• Calculate Voltage drop: Find minimum VD wire size, maximum length for any given wire size to stay within specified VD, drop percentage, actual number and percentage of Volts dropped.
• Conduit sizing for 12 types of conduit per NEC®: Find recommended size of conduit for combinations of #THW, #XHHW, and #THHN wires. Also calculates fill percentages, conduit cross-sectional areas, remaining areas and more.
• Find Motor Full-Load current per current NEC®: Works in 1ø or 3ø, synchronous and DC motors per NEC® 430-247, 430-248, and 430-250.
• Calculate Fuse and Breaker Sizes per NEC® 430-52.
• Parallel and derated wire sizing
• Calculate parallel resistance
• NEC Table number displays when performing wire size calculations
• Sizes overload protection per NEC® 430-32.
• Finds NEMA starter sizes per ICS 2-1988 (Tables 2-327-1 and 2-327-2).
• Calculates service and equipment grounding conductor sizes per NEC® 250-122 and 250-66.
• Convert between BTU and Kilowatts per Hour
• Circular MILs calculated for wire sizes
• Works as a standard math or electric calculator
• Quick and easy updates to future NEC® code revisions

This is the app I have been asking and waiting for. I have used another company's hand held calculator for quick accurate electrical system design calculations for some time. It was frustrating to carry a 2nd device when I aways had my iPhone with me. This app is easy to use, based on the most recent NEC release and has an excellent manual readily accessible. I highly recommend it to anyone who needs to design electrical power distribution circuits and or make sure their installations are NEC compliant. It is just as useful for estimating and creating BOMs for electrical work. The iPad version features a rotating screen for landscape use as well. Not much more to ask for. If you buy only one electrical app this is the one.
It’s awesome except I have to restart the app many times to get it to calculate
Wish this issue could be fixed ASA!! Seems the equal sign does t work?

Great Electrical Tool
I really like this app! It is one of the most useful apps I have on my phone. I have checked the voltage drop calculations on various 208v to 4160v, 3 phase circuits and I have not found an error yet. The interface is fast and intuitive once you get it down.
