I wouldn't consider it a hazard provided there is ready access to the electrical panel so that its switches can be accessed and turned off in an emergency. Perhaps it was simply labelled a generic "200V"? If your system only requires three phase operation or single phase 208, a neutral is not required. Do not attempt these tasks unless you are properly trained and equipped. Devices with motors will last longer because a three-phase system is more consistent. Moreover, it is common to refer to it as an Edison system, split-phase, or center-tapped neutral. 208 volt systems here usually measure around 215.
