電灯・動力共用三相4線式(でんとうどうりょくきょうよう3そう4せんしき)とは、200V三相と100V単相の電力を4本の電線・ケーブルを用いて供給する配電方式である。
, High-leg delta (also known as wild-leg, st … High-leg delta (also known as wild-leg, stinger leg, bastard leg, high-leg, orange-leg, red-leg, dog-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). The three-phase power is connected in the delta configuration, and the center point of one phase is grounded. This creates both a split-phase single phase supply (L1 or L2 to neutral on diagram at right) and three-phase (L1-L2-L3 at right). It is called "orange leg" because the L3 wire is often required to be color-coded orange. By convention, the high leg is usually set in the center (B phase) lug in the involved panel, regardless of the L1-L2-L3 designation at the transformer.e L1-L2-L3 designation at the transformer.
