I have a quick question, I want to verify the data that this online calculator provides.
a company installed some equipment for me and used 14-3 to power my panel. the 14-3 run was around 80 feet. the system voltage is usually between 24-26 volts DC. The panel current is usually around 1-2 amps, but can get as high as 7-8 amps depending on a dc motor that is powered out of this panel. we have had some issues with this panel because of this and before I present this to the installer I want to make sure I have all of my ducks in a row.
I used this online claculator I found to verify what i already knew, that 14 gauage wire is too small to run 6-7 amps with a 80 foot run.
I am sure it is correct because my voltage is 26-ish and we see it get down to the 22-23 volt range when we run the dc motor.
it looks like we should go with at least a 8 gauge cable for this run of 80 feet. what do you think?
