What's wrong with 'Grounding'?
Are you married? Have you ever had a conversation with your wife, being totally confidant that you understood everything she said, only to find out the next day that the words she used and the words you heard had two different meanings?
Grounding has entirely too many meanings. If you're an electronic guy, Grounding means the common of the power supply.
If you're talking about a fault-current return path, you're talking about an equipment Grounding conductor that has nothing whatsoever to do with grounding.
Article 250 is about Grounding and Bonding. They are for two totally distinct purposes. Trouble is, although the terms are defined in the beginning of the article, after the first few sections, the terms are mixed together and used interchangeably.
For example, 'equipment grounding conductor' should be 'equipment bonding conductor.'
'Grounded receptacle' should be 'Bonded receptacle.'
Switch yokes need to be Grounded should be Switch yokes need to be Bonded.
It's a mess. That's why so many continuing education courses have to do with Grounding and Bonding.
