Depends on what you are using it for, I think 680 -hot tubs limits you to 6 feet, and i think it's limited to 6 feet for service raceways.

Check out 356.10 and 356.12.
Type B can be longer than 6 feet if properly secured.
Typical Carflex is type B.

NO the six foot rule applies when using liquid tight metallic conduit. The metal
spiral inside the conduit can be used as your ground if you use approved
connectors & keep it six feet or less in length.
For non metallic conduit (what you are using) a ground wire is required for any
length conduit from just inches to hunderds of feet.

As I said.
If it is not type B it can't be longer than 6 feet. Yes there is the 6 foot equipment grounding rule on metallic flex, but the rule is for equipment grounding and not a limit on the length of metallic flex.

680.42(1) limits it to 6 feet for outdoor spa/hot tub installations.
230.43
(15) does have a 6 foot limit for a particular condition.
(16) does allow it with no limitation on lenght.

Is the 6 foot rule new?. I know I have in the past used lengths longer than 6 feet.

Now that I reread the section it allows 6 ft outside the unit and whatever you need inside the unit so I guess its certainly concievable depending on the routing inside the tub that you could ahve alength considerably over 6 ft total. In any case a ground is required to be run no matter what.

That would make sense to me but I don't see where it says that, unless there is a change in 2011 and that is what you are looking at.
