is there any code reference stating that you can only run it as a raceway of up to six ft.
As I said.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.
Check out 356.10 and 356.12.
Type B can be longer than 6 feet if properly secured.
Typical Carflex is type B.
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.
(15) Flexible metal conduit not over 1.8 m (6 ft) long or liquidtight flexible metal conduit not over 1.8 m (6 ft) long between raceways, or between raceway and service equipment, with equipment bonding jumper routed with the flexible metal conduit or the liquidtight flexible metal conduit according to the provisions of 250.102(A), (B), (C), and (E)
(16) Liquidtight flexible nonmetallic conduit
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.
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.
