Wire size calculation guidelines

Determining wire gauges to connect a pedestal to a rectifier or other external
distribution hardware is a very simple procedure, but it can be tedious if a lot
of external components are involved. A programmable calculator or computer
can help if it is going to be done often.
Too many wire gauges delivered to a site can cost more money than
The method
Using the maximum
current
in a conductor, determine the
length
that the
conductor must be (remember that the vertical portions are sometimes longer
than the horizontal portion) in order to meet the required maximum
voltage
drop.
