Electrician's Helper 2.2.3

Electrician’s Helper simplifies the process of referencing electrical codes and completing intricate calculations necessary for installations.

• Perform voltage, current, and power calculations in 3-phase delta and wye circuits.
• Determine the ampacity of a conductor according to NEC and CEC standards.
• Calculate voltage drop in a line based on various parameters such as length, size, current, and temperature.
• Calculate total box fill by specifying the size and quantity of conductors, straps, and clamps.
• Calculate the maximum number of conductors permissible in a raceway of a specific size as per NEC and CEC guidelines.
• Identify the appropriate raceway size for a group of conductors.
• Determine the maximum bend radius of a conduit.
• Calculate the maximum capacitor kvar for a motor along with the resultant current reduction.
• Identify motor current, heater current, required breaker, wire size, starter, and conduit size for a specific 3-phase motor.
• Find the full load current of induction, squirrel cage, and synchronous motors.
• Discover the locked rotor current of single or 3-phase motors.
• Estimate the Maximum Pull Tension.
• Calculate voltage, current, and kVA for both single and three-phase transformers.
• Perform fundamental Ohm’s Law calculations.
• Obtain decimal equivalents for fractions.
• Conversion between temperature scales.
• Access connector configurations efficiently.
• Retrieve specific information from NEC tables such as 311.60(C)(67-84).

Compatible with iOS versions ranging from iOS 12.0 to iOS 15.1.

Please be aware that Electrician’s Helper serves as a tool for referencing the codes used in NEC and CEC; it does not replace the code books themselves.
