General Operation

• Power On/Off: Press the On/C button to turn the calculator on or clear the current entry.
• NEC Compliance: The calculator is compliant with the last six NEC editions, from 1996 through 2011. The display will show the current NEC year being used for calculations.
• Ohm's Law: Use the Volts, Amps, Watts, and VA keys to perform Ohm's Law calculations. Enter any two values to solve for the third.
• Wire Sizing: Utilize the WireSz key for copper and aluminum wire sizing, considering single or three-phase systems, ambient temperature, and 100% or 125% ampacity.
• Voltage Drop: The VD% key provides voltage drop solutions, including minimum wire size and maximum length for a given wire size.
• Conduit Sizing: The Condit key allows for conduit sizing for 12 different types of conduit and various wire types.
• Motor Calculations: Keys such as HPm (Horsepower Motor), Starter, DFuse (Dual Element Fuse), and InsTrip (Instantaneous Trip) assist with motor full load amps, starter sizes, and breaker/interrupt calculations.
• Grounding: Use the Gnd key for service and equipment grounding conductor size calculations.
