LFMC as a ground

[augie47]

Art 250.118 address using LFMC as a grounding conductor and limits the use of the raceway as a grounding means to a 60 amp circuit on sizes 3/4-1.1/4.
On sizes larger than 1-1/4 " can LFMC be used as the sole equipment grounding means ?

Above 1.25" LFMC the conduit does not qualify as an EGC.

 

[flatlander]

In any case?

Here's the code wording, no mention for larger than 1.25". Also if it's used for flexibility then it must have a wire type EGC.

250.118(6) Listed liquidtight flexible metal conduit meeting all
the following conditions:
a. The conduit is terminated in listed fittings.
b. For metric designators 12 through 16 (trade sizes
3/8 through 1/2 ), the circuit conductors contained in
the conduit are protected by overcurrent devices
rated at 20 amperes or less.
c. For metric designators 21 through 35 (trade sizes
3/4 through 1 1/4 ), the circuit conductors contained in
the conduit are protected by overcurrent devices
rated not more than 60 amperes and there is no
flexible metal conduit, flexible metallic tubing, or
liquidtight flexible metal conduit in trade sizes
metric designators 12 through 16 (trade sizes
3/8 through 1/2 ) in the ground-fault current path.
d. The combined length of flexible metal conduit and
flexible metallic tubing and liquidtight flexible
metal conduit in the same ground-fault current
path does not exceed 1.8 m (6 ft).
e. If used to connect equipment where flexibility is
necessary to minimize the transmission of vibra-
tion from equipment or to provide flexibility for
equipment that requires movement after installa-
tion, an equipment grounding conductor shall be
installed.
