For Electrical Contractors, Designers, Electricians Save time, avoid costly errors & solve hundreds of electrical problems with the touch of a few buttons! Unlike a regular calculator, the ElectriCalc LT has custom "electrical keys" with common NationalElectrical Code (NEC) tables built-in, allowing you to solve Code-related problems quickly and accurately. It's a handy 1999 NEC Reference Tool that puts electrical/wiring answers at your fingertips!

• Solve Electrical Math Problems Instantly Solve for volts, amps, volt-amps, watts, kVA, kW, PF%, EFF%, and DC resistance.
• Copper or Aluminum Wire Sizes Calculates wire sizes per NEC 310-16 & 310-17. Copper or aluminum, 3Ø/1Ø, 60°C, 75°C, 90°C insulation ratings at 100% or 125% of ampacity. Adjusts wire sizes for ambient temperatures other than 30°C and for more than three wires in a raceway.
• Parallel & Derated Wire Sizes One-button parallel & derated wire sizing.
• Voltage Drop Calculations Lets you find: minimum voltage drop wire size, max. length for any given wire size and drop percentage, actual number and percentage of volts dropped.
• Grounding Conductor Sizes Calculates service and equipment grounding conductor sizes.
• Works as a Regular Calculator
• Durable and Portable
