When you talk about this breaker that trips is 2 breakers up stream from the transformer, is that feeding a disribution panel that feeds the transformer? does the breaker trip when you start the machine or just while it's running(under load). What is the amperage draw of the machine. What is...
Here are a few formulas for you to calculate voltage drop:
Voltage drop = 2 x K x I x L divided by circular mil
cir mil = 2 x K x I x L divided by desired volts dropped
max lengeth = cmils x desired volt dropped divided 2 x k x L
max current= cmils x desired volt dropped divided2 x k x L...
