NEC 517.2 Missing?

[Irving LaRue]

I was reading through 517 and found a reference for 517.2 from the 2017 code. I looked it up in my 2023 NEC code book I have and 517.2 is missing. I encountered the same problem elsewhere in 547. I don't see 547.5 - 547.19 anywhere in the code. I found some references to that code online. It used to cover equipotential planes. Can anyone answer this mystery for me? Thanks!

All of the definitions have been moved to Article 100. In previous codes the xxx.2 sections was reserved for definitions.
The rules in 547.5 and following were the wiring methods. Those are now found in Part II of that article starting at 547.20.
