	Subject - Delta or wye lucky1122 Sometimes with a delta configuration with the mid point of one transformer grounded you will get three separate pots sometimes one pot preconfigured. Since the single phase loads will be on the one transformer it may be required to oversize that transformer depending on whether or not the others are oversized. Since there is a high leg with a voltage of 208V to ground that wire must terminate on the B phase in a paneland must be tagged with orange colored tape or the equivalent whenever it is used to supply lighting loads or generally line to neutral loads. JimmyDee The only time I've encountered line to neutral loads was when someone that didn't understand the wild leg configuration hooked up a refrigerator and microwave to that leg. Needless to say, neither lasted more than a minute. Jim lctrc789 Yes I had a service call sometime ago in a church where the maintenance guy or one of the church goers was doing some of his DIY wiring and they didn't realize they had high leg, POOF.. many things they just added by running new circuits and installing the wild leg on a breaker slot got a higher voltage shot and were ruined and gone forever... I had to exlain to them how this was wired and drew them a small diagram and hopefully they learned for this expensive lesson. frenchelectrician that one common reason that most poco in my area are phasing out the delta service due wild leg and safety issuse there. i did look at my poco regualtions book [ new copy came in few days ago ] and they mention that the new comuster for 3 phase service will only get wye connection but extsting comuster still get delta but only upgrade to match main breaker only nothing more if go larger size most case they will encourge you to converted over to wye connetion asap Merci, marc
