[QUOTE="dennishoddy, post: 3590610, member: 5412"] We used that old 208V wild leg when I first got into the industrial field. Really popular because one could rob 120V from the A or C phase and power accessories on the machine tools. The problem with that was for some reason they always selected the C phase on the right. that resulted in a misbalance of power at the transformer with C phase at twice the amperage of A phase. It was pretty ugly until a complete rebuild of the system with 480V three phase done by commercial contractors after adding 200,000 some square feet to the manufacturing facility and replacing all of the old machine tools or their electrical systems. Spent many months in the cabinets upgrading them and replacing the motors. I did enjoy that type of work though. I do have some horror stories though about being told to hook up machine tools on a 480V system live on a greasy wood ladder with no insulating gloves. Bare handed, prior to OSHA. Do it or the person waiting at the door for your job will fill it today. [/QUOTE]
