Hello, this forum is the best by far.
My question is:
Is there a formula to determine what wire size I need for a "electrical" run:
Example:
I'm using 120VAC
Wire:Copper
Length:100ft
The wire will handle 15Amp at Mximum.
What wire gage (AWG)I need?
Is there a formula?
Thanks in advance.
José.

Let's take the simplest case scenerion:
-Voltage drope at 3%, I thinks that is what the code call for.
-Temperature: about 80F
-Only carrying conductor in conduit.
- End of run: Lighting

However, I have seen some formulas ONline, but I don't understand them just yet. I'll take a second look....

There are some additional factors involved in AC voltage drops. Rather than trying to calculate the reactive impedance of the cables, we use the voltage drop tables in the NEC or CEC.
This method has the additional advantage in that the results are accepted by the inspection departments.
