Why Is My Phase Converter Voltage High?
We get asked all the time, “why is the voltage of the one line so much higher than the other two?” All traditional phase converters are high leg delta. This means that when using your meter you will measure 120 volts to ground on two of the three lines, but around 240 volts to ground on the third. This is perfectly normal and will work just fine for most motor loads. Here are some pictures of what you might be seeing. Traditional phase converters create only the 3rd line. The other two lines are left untouched. In a phase converter, the …
