...Five great utilities to make your job easier
Updated for the current National Electrical Code! More features!
Electrical Conduit Fill/Size Calculator
based on the 2002 National Electrical Code (NEC)
Enter any combination of up to 30 different conductor sizes or types in any quantity and the calculator will determine the conduit size for every type of conduit recognized by the NEC .
Power Factor Correction - 3 Calculators in one
New feature! Allows you to choose either Voltage and Amperage input or Wattage input.
Most PF calculators require you to enter wattage information but with this calculator you have a choice.
You can enter only the current and voltage. No separate wattmeter is required.
Or, if you prefer, you can enter the Wattage instead of the current and voltage.
Then, enter the PF (actual if you know it or from motor nameplate information) and the calculator will tell you how many kVAr's to put on-line to achieve the PF you want.
The PF Correction calculator can also be used to select transformers. Instructions are included in the PF Calculator to determine transformer size.
Whether you are a first year apprentice, a master electrician, engineer, inspector, or a homeowner, you can use this software and learn from it.

Calculates the branch circuit demand loads, total demand load, main breaker size and the size of service conductors.
