The grounded conductor between two panels carries current during ___.

The grounded conductor between two panels is designed to carry current under specific conditions, primarily during normal operation and during fault conditions such as a short circuit. During normal operation, the grounded conductor serves as a return path for current from the load back to the source. In scenarios like a short circuit, the grounded conductor may also carry current as it helps in providing a path for fault current to flow back to the ground, facilitating the operation of protective devices such as circuit breakers.

Given this understanding, the grounded conductor is indeed involved during both normal operation and situations like short circuits, which justifies why the combined answer reflects these two conditions. The grounded conductor plays a critical role in ensuring the safety and functionality of the electrical system during these scenarios.
