Article 350 LFMC maxium length runnable.

[Crown Electrical]

Have reviewed this article several times and have found no restriction on how far LFMC can be run.

Is there a limit?

Thanks.

I think you will be limited by your ability to get wire thru long runs. AFAIK there is no limit

3/8" LFMC is limited to 6'. {350.20(A)Exception}

I had to use 3/8" LFMC to wire some rooftop mushroom exhaust fans. The MFG (I think they were Greenheck fans)supplies a pipe up through the fan to snake a raceway 1/2" LFMC wouldn't fit so I used 3/8" Specs called for LFMC could have been MC I guess. 3/8" probably not legal
