Electrician's Helper

Electrician’s Helper will take the hassle out of looking up electrical codes and doing complex calculations for installations.

With Electrician’s Helper you can...

●   Calculate voltage, current and power in 3 phase delta and wye circuits.

●   Find the ampacity of a conductor as per the NEC and CEC tables.

●   Calculate the voltage drop in a line based on length, size, current and temperature.

●   Find the total box fill by entering the size and number of conductors, straps and clamps.

●   Find the maximum number of conductors allowed in a particular size raceway based on NEC and CEC rules.

●   Determine what size raceway is needed for a bundle of conductors.

●   Find the maximum bend radius of a conduit.

●   Find the maximum capacitor kvar for a motor and the current reduction obtained.

●   Find the motor current, heater current, breaker required, wire size, starter and conduit size for a particular 3 phase motor.

●   Find the full load current of an induction, squirrel cage, and synchronous motor.

●   Find the locked rotor current of a single or 3 phase motor.

●   Estimate the Maximum Pull Tension.
 
●   Calculate voltage, current and kVA of single and three phase transformers.
    
●   Do basic ohm’s law calculations.

●   Find decimal equivalents of fractions.
