IEC Wiring Conventions
IEC Wiring Conventions
(OP)
Understanding the majority of the wiring conventions in most of the European prints I have come across, I have run across something I can not find information about. I am talking about a particular column (say column 2). Going into a 3 phase device the wires are labeled 221 222 223. On the load side they have 1221 1222 1223. I would have thought I should have seen 221 223 225 and on the load side 222 224 226. Can anyone direct me to some information where I can find out why the 1221 etc numbers or give me some feedback on them. Thanks
