When reducing electrical noise for electronic equipment, which fitting is acceptable to use?

Using a nonmetallic fitting is acceptable for reducing electrical noise in electronic equipment. Nonmetallic fittings often have properties that help to mitigate electromagnetic interference (EMI), as they do not conduct electricity and can act as insulators. This quality allows them to prevent the propagation of electrical noise that could affect sensitive electronic components, which is particularly important in environments where clear and consistent signals are necessary.

Additionally, nonmetallic materials can help in maintaining proper grounding and shielding where required by minimizing interruptions in signal quality that might arise from conducting materials. This is a key consideration in installations involving sensitive electronics, such as communication systems, where the integrity of the signals is paramount.

In contexts where electrical noise reduction is vital, opting for materials that do not disrupt the electromagnetic environment around sensitive components is essential. This choice helps ensure compliance with the relevant electrical codes and standards that prioritize the performance and reliability of electronic equipment.
