I have also added a conditions factor that takes ambient climate into effect. As engineer for CSG, I have verified the calculations and formulae as correct, yielding good results.
VOLTAGE DROP CALCULATOR PROFESSIONAL
For the sake of prudence and in order to comply with national and local code, secure the services of a qualified professional in your area. Although the notes did not say that they had MEASURED the voltage drop and that our calculations were incorrect, the implication was there.
VOLTAGE DROP CALCULATOR CODE
As of / we have had two notes that implied that code formulae and practices, and our method for calculation were very different and yielded substantial differences. That track record is far better than the national code for acceptable deviation. In the actual electronic and electrical tests in both commercial and residential, AC and DC applications, our calculations have been within one percent of the MEASURED voltage drop in every instance we have had the opportunity to check them. We strongly suggest that you use the results here as they are intended, estimates. If you need to calculate the size of the wire, you might want to consider using our wire size calculator. The results are returned as the estimated drop in voltage (the amount of voltage loss from original input in a conductor of given size and length), drop percentage, the load at most distant point in the circuit, and the conductor CMA. Enter the required data and click on Calculate. This is designed to give the approximate loss factors in a circuit ( AC or DC), including type of circuit, AWG (or KCMIL), amperage, length of circuit and type of conductor, for wire or circuit board. It remains the responsibility of the user to ascertain where flexible cords are suitable.This calculator requires the use of Javascript enabled and capable browsers. The current carrying capacity tables for flexible cords in BS7671 do not include options for different installation methods, results have been included for flexible cords for the whole range of installation methods. NEC Data: With this tab, the user can calculate an estimated voltage drop by using resistance and reactance date that comes straight from the National Electric Code, or NEC. It remains the responsibility of the user to ensure all data and assumptions are correct and that any cable used is suitable for its intended purpose. Take advantage of our DC Voltage Drop Calculator for any calculations that you need, and make sure to bookmark this page for handy reference, or share on social media. In order for us to provide this information as a guide certain assumptions will have been made The calculation is derived from BS7671 Requirements for Electrical Installation, IEE Wiring Regulations, and is based on the voltage drop selected at 230 and 400 volts. The recommended cable sizes are based upon information provided by the user and are intended as a guide only.
