Final answer:
The color code for Phase B high leg in a Delta High Leg system is orange. This standard color coding helps in identifying the various phases, with the high-leg carrying a higher voltage.
Step-by-step explanation:
The Delta High Leg color code for Phase B high leg is orange. In a typical three-phase, four-wire delta system, also known as a high-leg delta system, the standard coding is black for Phase A, red for Phase C, and orange for the high-leg, which is Phase B. This color coding is important for identifying the high leg, which carries higher voltage and is intended to balance the system loads.
