Drop may be significantly larger during surge or motor starting conditions -- sometimes in the 15% to 25% range if other devices on the system can withstand this momentary dip. The 2% voltage drop rule suggests that the voltage drop in a circuit should not exceed 2% of the supply voltage to ensure efficient operation. 12 volts is considered safe It involves applying a load and measuring voltage drop and current to calculate resistance. The circuit length accounts for the full "round trip" the current makes, from the power source to the load and back. Imagine we have a DC lamp that needs, at least, 12V to work , but, due to voltage drop, supplies 10V. Voltage drop Line-Line is given by: AC Voltage Drop Calculator Considering Power Factor.
