I have a laboratory installation with a 230 volt corner grounded delta system.
The lab users will be plugging in 220 volt single and three phase instrumentation from Euorpean manufacturers.
The installation has 220 volts wired to the receptacles, without regard to the phases. In other words, some single phase, two pole, three wire receptacles are connected between A and C phases (line to line). Other receptacles are wired between A (or C) and the grounded B phase (line to neutral).
Will there be a problem with 220 volt appliances connected between the A&C hot phases (line to line)? I am concerned about a possible lack of internal fusing on both lines if the appliance is expecting to see a neutral connection. (On US appliances, I see a sinlgle fuse on the polarized hot conductor only.) Also, is there a possible problem with chassis grounds or other connections to the hot conductor?
