2017 NEC 680.21(A)1

I just want to be sure I'm understanding the changes to this section. In a noncorrosive environment AC cable would be adequate for the motor branch circuit.

Yes...any chapter 3 wiring method.

That's how I saw it I just wanted confirmation.

When do you get on the 2017 Code?

Heck, you can use nm for pool motors in a non-corrosive environment. I guess they make mc cable for corrosive environments.

Rick might know better but going by the past early to mid 2018.

That's probably right. I was just asking because I like to have the answers well before I do an inspection.

But.....they lacked (and I argued this point) adding the real definition to such an area. It is way too broad in 680.14 (A). However, I hope that issue will be addressed in the 2020 process.
