Voltage Drop

Max Voltage Drop Max Length
2% Voltage Drop
3% Voltage Drop
5% Voltage Drop
Good design practices limit wire ampacity due to over current to 80% of rated ampacity under most circumstances.
The wire size will not be able to handle this load and it will cause catastrophic failures.
Good design requirements should limit overall voltage drop to less than 5%.
