Electrician's Helper

Electrician's helper provides many useful calculators and converters for electricians and anyone working with power distribution.
Both the NEC and CEC codes are covered.

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.● Calculate voltage, current and kVA values for single and three phase transformers.● Find the locked rotor current of a single or 3 phase motor.● Do basic Ohm’s law calculations.● Find decimal equivalents of fractions.● Convert temperature scales.● Look up connector configurations.
