Track Bus voltage drop calculator

If locomotives slow down in the same location each time it might be due to a voltage drop due to wire length.  

***Note,  you must DOUBLE the length of your cable!!!

 example 1     100 total feet of 14 AWG wire and 14V / 5amp system.

A typical HO layout   18% loss!




 * @ 68°F or 20°C

** Results may change with real wires: different resistivity of material and number of strands in wire
