Is there any reason you can't use romex to feed an outdoor spa or pool sub panel on a house? I keep seeing conduit in attics and it is making me second guess myself.
That article is for the motor. You can wire the motor that way not a panel. The panel would need a feeder which is in 680.25What about 680.21(A)(4)? Wouldn't that allow for NM cable to be used for the pool panel?
Ok, I can accept that but don't understand why. Why is it ok for just the motor or a sub panel but not ok for a POOL sub panel? :?That article is for the motor. You can wire the motor that way not a panel. The panel would need a feeder which is in 680.25
A pool sub panel usually has an underwater light (wet niche luminaire) run from it. 120 volts underwater, and chest height of a person holding on to the edge, makes the CMP very nervous. They want you to be very careful with that ground....Why is it ok for just the motor or a sub panel but not ok for a POOL sub panel? :?

I suspect that historically the no-NM rule came into NEC before there were GFCIs. Also a good solid ground will remain operational longer than the typical GFCI receptacle. Not sure how good, by comparison GFCI breakers are.That makes sense but wouldn't the GFCI be a better protection for some sort of short in the pool light?

Yes, and there's a #8 bond wire inside the niche and a bond wire on a lug on the outside surface of the niche. Each is there for a different catastrophic failure.
Besides, old GFCI receptacles used to fail and remain hot.
