Patrick, with <tic> `~ granted under significant load there should be a voltage drop ( which I stated in correctly ) and as I learned it is the amps that do the work so which do you think is needed the most for Ron's VAC?

  The formula for voltage drop is: Voltage Drop = I times R


  I = current in Amps
  R = Resistance of the conductor in Ohms


  So for any given length of wire, the resistance will increase as the size of the conductor deceases and the voltage will drop for any given level of draw (amps). 


  In other words in your case, lets say you put a load on the circuit of a given length that draws x amount of amps, you will see a voltage drop as the conductor size reduces (resistance increases). 


  As the formula is stated, if you have no "current" draw, you will have no voltage drop, but why would you have a circuit if you didn't put a load on it?  In other words the voltage will drop.


  This will calculate it for you.

    Ron .. I think you are referring to current or amperage.. Voltage won't show a drop.. 14 gauge is a no no.. except for lighting basically.. Low current drain.

      For a 120 VAC system, can anyone tell me what the voltage drop will be over a give length of 10 gauge, 12 gauge and 14 gauge copper wiring?



      Thanks
