3 phase panels and sub panels


Nobody told you to short across two hot legs. You just didn't understand three phase nomenclature. Now you know everything needed to work on three phase power.

Oh the other thing with the voltage reading some area you may read higher than standard voltage due some POCO will set the transfomer(s) little higher than normal so once a hevey load kick on it will be right on the target.

So therefore with wye connection as other tell ya it is on right on spot and if you actally have 220 volts phase to phase then you will get 127 volts across the line et netural if other voltage it will prorated up higher like 240Y138 volts

michael825 any two hots are 215 and any hot and neutral are 123. i dont understand what you mean AC{OR AB} to neutral. do you mean for me to to simultaneously read two hots and the neutral also there really is no ground bar
The reading is on high side of 208 network but you do have 208Y120 volt system and that reading I have see it pretty often on unloaded system. ( BTW that voltage you describe is not a delta format at all }

Merci,
Marc
