Introducing the
ElectriCalc® Pro
Now NEC®-Updateable!
The ElectriCalc® Pro is an invaluable calculator for today’s busy electrical professional. Unlike a regular calculator, it has intuitively labeled “electrical keys” and conforms to the 2008 (and 2005, 2002, 1999, 1996) and futureNational Electrical Codes, allowing you to solve Code-related problems quickly and accurately. The most common NEC tables are now at your fingertips! An important feature of the ElectriCalc Pro is that it is programmed to accept future NEC changes, allowing you to conveniently install future Code editions in a few simple steps.
The ElectriCalc Pro instantly solves for the following:
• • • •• •
• • • • • • • •
Kirchhoff’s Law Ohm’s Law Volts, Amps, Volt-Amps, Watts, kVA, kW, PF%, EFF%, and Resistance Copper or Aluminum Wire Sizes Parallel and Derated Wire Sizes Voltage Drop Wire Sizes, % and Actual Voltage Drops, Voltage Drop Distances and Wire Resistances Kilowatt hours and BTU’s Parallel Resistance Grounding Conductors Sizes Motor Full-Load Amps Overload Protection Sizes NEMAStarter Sizes Conduit Sizes And much more!

Your ElectriCalc Pro is now updateablefor future National Electrical Code® editions that are updated every three (3) years. To upgrade your unit, follow the instructions below: 1) Purchase the NEC Update from CI (see pricing / details from CI’s Web site: www.calculated.com or call 1-800-854-8075). This Update is in the form of a chip that contains the new Code. 2) Once you receive the NEC Update chip, you need to install it in yourElectriCalc Pro: a) Turn calculator off. b) As a precaution, remove the battery (located back of calculator, top of unit) by sliding battery door out with your thumbnail. Set aside. c) Using a screwdriver, pop out the square tab located in the middle section on the back of your calculator. d) Replace it with the new update tab by inserting it into the slot. e) Replace the battery door. f) Turncalculator on. Your calculator is now updated and ready to use.
