Ron if this is a circuit over 250v. to ground then it might be a violation. 250.97 If this is a Service raceway and this is the method of bonding then it might be a violation. 250.92 Your not giving us much information. I don't think it's a good installations but I've seen it done and can't really argue that it's not "effectively bonded" based on my understanding of the term. In technical terms it's "pig work". You only have to bond one end of a raceway sometimes, even on Service raceways. Now what brings up this question?
