In conduit systems, why is it important to use the correct fitting for different conditions?

Using the correct fitting in conduit systems is crucial for ensuring compliance with electrical codes. Electrical codes are established to guarantee safety, reliability, and efficiency in electrical installations. Different conditions, such as the environment in which the conduit is installed (outdoors, indoors, exposed to harsh conditions, etc.), require specific types of fittings designed to withstand various stresses, protect against water ingress, or accommodate thermal expansion.

For example, using fittings specifically rated for outdoor use ensures that they can handle exposure to moisture and corrosion. Compliance with these codes helps prevent accidents such as electrical shorts, fires, or system failures, ultimately protecting both the property and the individuals who may interact with the electrical systems. Thus, the importance of selecting the right fittings goes beyond aesthetics or cost; it is fundamentally tied to safety and adherence to legally mandated standards.
