Hi all,
In reviewing a test we have come across one question that no one can agree on.
In a 120/208Y system You have a report of what appears to be a missing C Phase. You test at the Main Panel OCPD--What voltage would you expect to see when testing from C Phase to Neutral
A. Zero Voltage
B. 104 Volts
c. 330 Volts
d. Voltage will be unstable
I am saying that it will be D--- not really unstable but more likely variable and less then 120 volts.
I'm going to try using drawings and pics to see if I can get the others to see it my way:thumbsup: tomorrow.
I'll let you all know what happens with that, but any info you can give would sure help!
Thanks
Rich
