The ElectriCalc Pro is an invaluable calculator for today's busy
electrical professional. It's a complete NEC Reference Tool that
puts electrical/wiring answers at your fingertips! And, it's
updateable for future NEC revisions!
Unlike a regular calculator, the ElectriCalc Pro has intuitively
labeled "electrical keys" and conforms to the National Electrical
Code, allowing you to solve Code-related problems quickly and
accurately. Common NEC tables are built in, providing instant
solutions for the following:
- Solve Electrical Math Problems Instantly
Solve for volts, amps, volt-amps, watts, kVA, kW, PF%, EFF%, and
- Copper or Aluminum Wire Sizes
Calculates wire sizes per NEC 310-16 & 310-17. Copper or aluminum,
30/10, 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
It's a Voltage Drop Calculator -
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 per NEC
Tables 250-66 & 250-122.
- Find Motor Full-Load Amps per NEC
Works in 1Ø and 3Ø with the new expanded tables for 3Ø induction
(to 500 HP) and synchronous (to 200 HP) motors per NEC 430-148 and
- Computes Fuse & Breaker Sizes per NEC 430-152
Built-in solutions for: single and dual element fuses,
instantaneous trip breakers and inverse time breakers.
- Sizes Overload Protection per NEC 430-32
- Automatically Finds NEMA Starter Sizes
- Conduit Sizing for 12 Types of Conduit!
Per NEC Tables 1, 3, 4, and 5 of Chapter 9, allows sizing of
all common conduits for any combination of #THW, #XHHW and #THHN
Wires. Plus, gives fill percentages, cross-sectional areas,
remaining areas and more.
