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). 4 Wire High Leg Delta Transformer Connection Electrical ... pleted high leg delta circuit diagram; pleted high leg delta phasor diagram; Conclusion; 1. Introduction. The most common mistake made when calculating the voltage magnitude across the high leg of a 4 wire delta transformer secondary with a center tapped winding is not including the phase angles when you sum the voltages. Four Wire Delta Circuits – Continental Control Systems, LLC This is the most common four wire three phase delta service and is essentially a 240 volt, three phase, three wire delta service with one of the 240 volt transformer winding center tapped to provide two 120 Vac circuits, which are 180 degrees out of phase with each other. 240V 3 Phase and 240V Single Phase • OEM Panels It’s like 120 240V but also provides 240V 3 Phase for large loads (Machinery, etc.). It’s often called “Wild Leg” of “High Leg” Delta because one leg (Phase B) is different. THE GOOD – It’s inexpensive for the power company and it provides 120V 240V Single Phase and 240V 3 Phase. 120 240 VAC SINGLE SPLIT PHASE & MULTI WIRE BRANCH CIRCUITS • 120 VAC branch circuit loads are connected between a breaker on Phase A (Hot Leg L1, Red wire) and Neutral (N, White wire) as shown for Branch Circuit 1 or between a breaker on Phase B (Hot Leg L2, Black wire) and Neutral (N, White wire) as shown for Branch Circuit 2 480 input 240 120 output control transformer wiring mystery 480 input 240 120 output control transformer wiring mystery ... The only reason the wiring diagram is so specific about the connections, ... As for teh 120 240 vs 120 OR 240, there is NO difference. For 120 240, you wire the X2 and X3, etc just as for 240V, but you get the voltages as Thermite has mentioned. 240V 3 phase pros and cons Mike Holt Code Forum Thanks Mike. I know you can get single pole 277 volt breakers. The panelboard was 120 240 3 phase 4 wire. The extra spaces were on the high leg a factory owner wanted to use 120 240 volt circuit breakers to feed 208 volt lighting ballasts. This issue has been resolved. I thought I would post it for an example of what I interpret as a code ... 3 Phase High leg Delta breaker in single phase box 3 phase 240 volt 60 amp Square D QO breaker in a single phase box. The Highleg Red, Wildcat leg (208 volts to neutral) directly feeds the 3 phase 3 pole breaker via a wire from the watthour hour ...
