ElectriCalc Pro: Electrical Problem-Solving Calculator

Compliant with 2023, 2017, 2014, 2011, 2008, 2005, 2002, 1999, 1996 NEC®

Electrical Contractors, Designers, Electricians and Lighting Specialists solve tough electrical calculations in seconds and deliver those solutions in conformance with the latest NEC®. The ElectriCalc® Pro is a complete electrical reference tool that will save time, trouble and money. Update to future NEC® updates with an easy-to-install kit. Includes Armadillo Gear™ protective Hard Case.

It helps you solve for:

• Wire Sizes
• Integrated Voltage Drop
• Conduit Sizing
• Motor Full-Load Amps
• Fuse and Breaker Sizes
• NEC® Table Number displayed when performing Wire Size calculations
• Service and Equipment Grounding Conductor Sizes
• Enter BTU to find Kilowatts per Hour
• Enter Kilowatts per Hour to find BTU
• Parallel Resistance
• Ohm's Law Calculations - enter any two values to solve for the third
• Circular MILS wire sizes

NEC 2014 Compliance Notice. The 2014 NEC Code has been examined and there are several impacts as it relates to calculations in Model 5060, 5065 and 5070. Setting the calculator to NEC 2014 will make it compliant to the new code.

NEC 2014 modifies the upper voltage range for Table 430.250, changing the range from 550V - 600V to 550V - 1000V.

NEC 2014 revised the internal diameter/area for Electrical Nonmetallic Tubing (ENT) (Table 4, Article 362)
