True or False: Fittings and connectors must be used only with the specific wiring methods for which they are designed.

The statement is true because fittings and connectors are specifically designed to work with certain wiring methods, according to the National Electrical Code (NEC). Each type of fitting or connector ensures that the mechanical and electrical characteristics align with the requirements of the wiring method it is intended for. Using fittings and connectors outside of their designed application can lead to safety hazards, including poor electrical performance, potential overheating, and even fire risks.

Adhering to this guideline guarantees that the fittings and connectors maintain the integrity of the wiring system, provide proper strain relief, and ensure that protective measures, such as moisture resistance or environmental protection, are effectively utilized. This is critical in installations where safety and reliability are of utmost importance. Overall, using fittings and connectors appropriately enhances the overall safety of electrical installations, which is a key principle of the NEC.
