It helps you:

• Work directly in and convert between Amps, Watts, Volts, Volt-Amps, kVA, kW, PF% and EFF% and DC Resistance
• Calculate wire sizes per NEC®; Copper or aluminum, 3Ø/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
• 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. Find sizing of all common conduits for any combination for THW/THHW, XHH/XHHW and THHN/THWN wires. Plus, gives fill percentages, cross-sectional areas, remaining areas and more
• Find Motor Full-Load Amps per Current NEC®. Works in 1Ø and 3Ø with the new expanded tables for 3Ø induction (to 500 hp) synchronous (to 200 hp) and DC motors per NEC®.
