<I would call 115V 30A a common business circuit; it's certainly exceedingl <common on minicomputer power controllers. What else do folks plug the <Twist-N-Locks on their DEC 861C power controllers into? Special. Most places where I've seen systems installed for the first time that circuit had to be added. Even at DSG, PK3 and the Mill I had to have facilities add circuits for some things as that was not the normal distribution in the lab areas. My reference was that the average business and building unless prepped will only have 15 or maybe 20A outlets in place. Older buildings those will be in short supply. Then again NYC is where I have most of that experience. Allison
