Determine single phase voltage drop for a cable of known size, length and maximum demand

This tutorial will take you through the exercise on page 172 of your workbook.
This problem provides the actual single phase voltage drop, in volts of a particular cable of known length and maximum demand.

Mate you have the best videos on KZbin for max demand and cable selection you have really helped streamline and summarise G107 for me. Thank you!

Glad it's been of use to you.

hi mate thank you, really your videos help me a lot. i have a question i cant table 40 or 41 in As 3000.

Hey mate, thanks for the explanation, however I get 14.01v on my sub mains calculation. Not sure what I’m doing different than you due to your value ?

Would anyone be able to recommend a VOLTAGE DROP CALCULATION video for 3-phase systems and CEC (Canadian Electrical Code), please?

[@sarkisishac7346]

for the consumer mains isnt it 8.71v?

The 5% volt drop in three phase 20.75 v Bc you have them in 3 phase

@@jhonrivero6600 this video is about voltage drop I a single phase cable of known size, length and maximum demand. Nevertheless, if it were about three phase the maximum value would be 20 volts as calculations are based on 400v.
