Its standard practice around here to run 10/3 w/g to feed the pool sub-panel in one family homes. 680.20(a)(4) (2008) allows it.

Dave there is no 680.20(A)(4). I believe you mean 680.21(A)(4) and that does not pertain to panels-- that is only to the motor
 
New devopment on this same job. Now they want to add a hot tub which will also be fed from the main panel ( not from the pool panel). Does that mean I need to follow the same rules or is a Romex branch circuit ok because it is not a feeder? The hot tub disconnect (which will be a gfci breaker) will also be mounted on the exterior of a perimeter wall of the house.

The wiring between the service panel and GFCI breaker would be considered a feeder so the same rules apply.

If the outside hot tub disconnect were just a switch it would be considered a branch circuit and Romex would be acceptable?

This is true but absolutely ridiculous. I brought this up at our state meetinglast year and the cmp members agreed and thought the wire to the disconnect whether it had overcurrent protective device or not should be considered a branch circuit. Of course that is not what the NEC states. I wrote a proposal to change this-- we'll see.

If this is a residence then the wiring for the tub on the inside of the dwelling may be nm cable. 680.42(C)

That would only apply to the wiring between the GFCI/Disconnect panel and the tub control panel. The wiring to the panel that contains the GFCI breaker would still need to comply with 680.25.

I disagree. Where in that section does it differentiate . It states the interior wiring may be chapter 3. Since every tub on the exterior of the building would need a disconnect what good is this article if it didn't apply to the entire run. Is not the cable from the panel part of the hookup to the tub. This section talks about the interior wiring to the outdoor unit.

(C) Interior Wiring to Outdoor Installations. In the interior
of a dwelling unit or in the interior of another building
or structure associated with a dwelling unit, any of the
wiring methods recognized or permitted in Chapter 3 of
this Code that contains a copper equipment grounding conductor
that is insulated or enclosed within the outer sheath
of the wiring method and not smaller than 12 AWG shall be
permitted to be used for the connection to motor, heating,
and control loads that are part of a self-contained spa or hot
tub or a packaged spa or hot tub equipment assembly. Wiring
to an underwater luminaire shall comply with 680.23 or
680.33.

Does this part apply to Branch Circuit to a Hot Tub?...

"Wiring to an underwater luminaire shall comply with 680.23 or 680.33."

If it does then an insulated ECG is required.

Imo, that refers to a nonlisted unit or the wiring to the light itself
