Voltage Drop
Forum rules
Dear convert-me.com forum visitors,
Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.
All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page
Thank you for being with us and sorry for any inconveniences this could caused.

What size aluminum conductor should I use? Service line for a poultry house, 120/240 volt service, 155' from trasformer pole to load site. Estimated load is 190 amps and I can only have a 1.5% voltage drop.

The answer, of course, is that you shouldn't use aluminum at all.jcash wrote:What size aluminum conductor should I use? Service line for a poultry house, 120/240 volt service, 155' from trasformer pole to load site. Estimated load is 190 amps and I can only have a 1.5% voltage drop.
The answer is 350 kCmil wire. tough to find. You'll want to use 4/0 copper in real life.
Check out http://www.electrician.com/vd_calculator.html for a handy voltage drop calculator.
http://www.powerstream.com/Wire_Size.htm has a good reference for finding resistivity of copper wire. all you'll need to remember is that aluminum wire has a k 1.64 times that of copper, and you should be able to convert.

I'm not sure what "HCM size" is. AWM 4/0 wire (American Wire Gauge) is 120 mm for metric standard.peter upton wrote:I am using 4/0 welding cable; what is the equilivent in "HCM" size?
