[AMPS] Question About Correct Phase for 240V Transformer Primary Windings ???

[UNCRICHIE7@aol.com]

Hi Fellas, A question for you High Voltage Transformer Guru's. I have an 
unlabeled transformer. I have found the primary windings. This transformer 
can be powered by 120 or 240 volts. Heres the question. How can you tell the 
phase of the windings in order to properly set up for 240 operation. I'm not 
sure if this will help determine it but the pig tails of the windings are 
Brown/Black and the other is Blue/Yellow. As always any help would be greatly 
appreciated...  Thanks, Kurt, K3KL...
