What is the maximum size conductor that can be terminated using a 200A load break elbow?

The maximum size conductor that can be terminated using a 200A load break elbow is indeed 250. Load break elbows are designed for specific current ratings and conductor sizes, balancing the need for sufficient capacity while ensuring safe and reliable operation.

In the case of a 200A load break elbow, while it is rated for a continuous current of 200A, it can accommodate larger conductors up to 250, allowing for efficient transfer of electricity while adhering to safety standards and providing some headroom for potential overloads. This sizing consideration is crucial, as using conductors that are too small can lead to overheating and potential failure in the system, while larger conductors can help minimize voltage drop and enhance performance along the distribution line.

The other options, including 150, 200, and 300, do not reflect the correct maximum conductor size for this application as they either fall below or exceed the designed specifications of the elbow, which is key to maintaining system integrity and performance.
