I'm perplexed. I work in the electrical department at a Minnesota State University. Over the years, several various departments on campus have ordered new tools and lab equipment. Most of this equipment is intended for use in large commercial applications. Examples of some of these machines are, milling machines, CNC, Autoclaves, Spectrum analyzers, etc. It seems to never fail that these devices are designed to operate at 230-240 volts, and often times the manufacturer will not want this equipment connected to 208 volts. I just recently connected a new Autoclave, that requires single phase 230-240 volts. The manufacturer provided an optional boost transformer to bring the voltage up to acceptable levels. Why would these machines be designed so often to operate at 240 volts, when they have to know that a majority of the time they will be used at facilities that most often will only have 3-phase WYE power?
