Hello We sometimes come across products that employ a Nyloc nut as the sole means of securing (preventing accidental loosening of) a protective earth connection on a threaded stud.
I’ve heard various views on the acceptability of this type of construction - some consider it OK provided the temperature is not high enough to cause the nylon insert to soften, others think that a separate spring/serrated washer is required since the nylon cannot be depended on in the longer term. I’d be interested to hear the views of others, particularly any CB or similar labs. I failed to uncover any IECEE decisions on this subject.
