1月23日的Electrician's Helper应用程序分析

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. ● Convert temperature scales. ● Look up connector configurations. ● Look up NEC tables 311.60(C)(67-84) Tested with iOS 12.0 thru iOS 15.1 Please note that this is a calculator for codes used in the NEC and CEC. It is not a replacement for the code books.
