I asked the inspector of the 6' whip rule, and here reassured me that it was for light whips only and not for the water heater that I tryed to apply it too! :roll:
IE: That straping was required unless it was a light whip!

the inspector wants to know if an aluminum whip is approved for grounding path and wants to know what the difference between a whip and mc would be i try to tell him mc has factory wrapped wire and our whips are made to spec and are reguired to comply with pipe fill codes plus use a ul approved grounding connector and even with specs on the material nothing on the flex says approved grounding path but the ur listing does say it meets art 250 standards
All the MC cable I have seen has the mylar binding tape surrounding the conductors,a whip will not.
The follwing link will also show you the difference in the construction of MC & whips.

Fixture whips are usually made from 3/8" FMC. In lengths 6' or less, 3/8" FMC is approved for grounding with the proper connectors.
Based on 110.2 the "whips" you are using are subject to approval.
The whips that are installed in this area normally carry a UL label as shown on the attached.

Some have a whip with a UR, but those are one which have come as an "assembled" unit with the whip supplied by the factory as part of a listed Assembly.

That was the answer for the OP from the OP's question...and agreed.

Greg,
I'm not in disagreement, but I was addressing his Post #3. My post was partly generated by incidents where E/C's have installed "pre-assembled"
whips purchased from a third party. In those cases we have normally asked for the UL: (NRTL) listing of the assembly.
The use of a UL listed connector an a "purchased assembled whip" is not normally sufficient to inspectors in this area.
