High leg delta
High leg delta (also known as wild leg, stinger leg, bastard leg, high leg, orange leg, or red leg delta) is a type of electrical service connection for three phase electric power installations. It is used when both single and three phase power is desired to be supplied from a three phase transformer (or transformer bank).I learned I have 3 phase "high leg" at my new location ...
3 phase machines with low voltage controls require that you identify the high leg and make sure it is not feeding the control transformer. Connect either of the low legs to the transformer, and note the tap.3 Phase 4 Wire Panel High Leg Electrical Contractor Talk
3 Phase 4 Wire Panel High Leg We are replacing an old panel that is from the early 70's. 3 phase 4 wire delta service in a condo unit. This is the first 3 phase system we have encountered in residential situation.Stumped by the Code? Requirements for Identifying the High ...
A. On a 4 wire, delta connected, 3 phase system, where the midpoint of one phase winding of the secondary is grounded (a high leg system), the conductor with 208V to ground must be durably and permanently marked by an outer finish orange in color or other effective means [110.15].Four Wire Delta Circuits – Continental Control Systems, LLC
The high leg or phase with the higher voltage as measured to neutral has traditionally been designated “Phase B”. A change to the 2008 NEC now allows the high leg of a four wire three phase delta service to be labeled as the “C” phase instead of the “B” phase.120 240 Volt 3 Phase Delta High Leg Electrician Talk ...
120 240 Volt 3 Phase Delta High Leg Ok I have a question about a high leg delta transformer. I know that phases A and C to neutral you get 120 and that phase B to neutral you get 208.Can a 3 phase QO load center be used on a 240V ``high leg ...
The problem, however, is with the phase neutral on the 3rd phase: it measures 208V, which is not a usable downstream voltage since it is too high. This is what gives the system its nickname ``high leg``. This high leg is commonly the B phase, but could be the A or C phase.
