Which statement is true regarding the use of fittings and connectors?

The statement regarding fittings and connectors being compatible with specific wiring methods is accurate because the use of fittings and connectors in electrical installations requires adherence to specific standards and guidelines. Each type of wiring method, whether it be non-metallic sheathed cable, conduit, or armored cable, has its own designated fittings and connectors designed to ensure proper electrical connections, mechanical support, and protection against environmental factors.

Compatibility is crucial for maintaining the integrity and safety of the electrical system. Using the appropriate fittings and connectors helps to create a secure and efficient electrical installation that complies with the National Electrical Code (NEC) and other relevant safety standards. This not only ensures reliable performance but also minimizes the risk of incidents such as short circuits, electrical shocks, or fire hazards caused by improper connections or materials.

The other statements incorrectly suggest that fittings can be universally applied without regard to the requirements of the wiring method or that they have limited applications, which does not reflect the importance of compatibility in electrical installations.
