In an open delta with single-phase loads, the high leg must be identified by _____.

A) using orange wire
B) tagging
C) both a and b
D) neither a nor b

High Leg

In electrical systems, a term referring to a conductor in a delta connection that has a higher voltage with respect to ground than the other two conductors.

Open Delta

A transformer connection method using two transformers to form a delta configuration, typically used when one transformer of a three-phase system is out of service or for economy in a lightly loaded system.

Single-Phase Loads

Equipment that operates on a single alternating current (AC) power phase, usually seen in residential and light commercial settings.

  • Acquire knowledge of the specific factors involved in linking transformers to three-phase systems.

Final Answer :
C
Explanation :
In an open delta with single-phase loads, the high leg (also known as the wild leg, power leg, or stinger leg) must be identified for safety and compliance reasons. This is typically done by using an orange wire for the high leg and tagging it appropriately to ensure clear identification. Both methods are used to prevent confusion and ensure that the high leg is easily recognizable, which is crucial for safety and maintenance purposes.
