Amperes enter the maximum current in amps that will flow through the circuit. The most common commercial building electric service in north america is 120 208 volt wye which is used to power 120 volt plug loads lighting and smaller hvac systems.

Once all the fields are entered the results will appear. The 5 3 voltage drop for the above branch circuit exceeds the nec s recommendations of 3 but it does not violate the nec unless the 16 ampere load is rated less than 113 6 volts. Voltage drop calculations dc single phase calculation the voltage drop v in volts v is equal to the wire current i in amps a times 2 times one way wire length l in feet ft times the wire resistance per 1000 feet r in ohms ω kft divided by 1000. For most 120 240v systems using cables of adequate ampacity voltage drop is not a concern unless cable lengths are well over a hundred feet.

This free voltage drop calculator estimates the voltage drop of an electrical circuit based on the wire size distance and anticipated load current. For motors it is recommended to multiply the nameplate fla by 1 25 for wire sizing. Operating voltage 113 6 volts. In addition experiment with the resistor and ohm s law calculator or explore hundreds of other calculators addressing math finance fitness health and more.

Voltage drop 6 4 volts 6 4 volts 120 volts 5 3 volts drop operating voltage 120 volts 6 4 volts. Single phase voltages are usually 115v or 120v while three phase voltages are typically 208v 230v or 480v. To get voltage drop calculation results you must enter data in all fields including parallels. In larger facilities the voltage is 277 480 volt and used to power single phase 277 volt lighting and larger hvac loads.
