Rescapt:

Not necessarily. I just had a transformer that was installed 2 years ago and we relocated it. I noticed where the inspector at the time had required gouging the crap out of my electrical equipment had been done that rust had built up. Surely, you would admit that when the electrical panel rusts out around a bonding connection you have defeated the simple defination of bonding. Perminent. It does not say perminent until it rusts out.
