Hello my name is and I will be happy to assist you.

You asking,

"voltage deliver to saw is it simply dividing 1200 by 120"

This is the calculation for Amperage witch is 1200/120=12 Amps

Customer: replied 1 year ago.
ok its asking what voltage is delivered to the saw
Expert:  Papatrexas replied 1 year ago.

what is the amperage of the saw?

If it is 12 Amp then you will have 5% =6V drop

corrected calculation

A #12 wire circuit 300 ft long will have a voltage drop of 19.2 %. This will provide 97V which is unacceptable. At that distance you'll need a #4 copper conductor for a 20A circuit.
