What should be avoided when conducting continuity tests in multiwire branch circuits?

When conducting continuity tests in multiwire branch circuits, it is important to avoid removing receptacles that depend on continuity because this can lead to inaccurate testing results. These receptacles are integrated into the circuit, and their removal may break the continuity path that needs to be tested. This disruption can yield misleading information about the integrity of the circuit because it alters the normal configuration and may mask existing issues within the wiring.

In multiwire branch circuits, the continuity tests are performed to ensure that all conductors are properly connected and functioning as intended. If conducting tests with disconnected or removed receptacles, the tester might not detect problems in the circuit that would be present during normal operation. Therefore, maintaining the continuity of all components within the circuit scheme is crucial for accurate testing and validation of the circuit's operational integrity.
