6 foot limit of liquid tight for hot tub

[Stevenfyeager]

One electrical inspector some years ago told me that I used more than 6 foot of liquidtight to a hot tub and that is not allowed. He didn't make me change it but, was he right ?

680.42(A)(1) in the 2023 code doesn't show a maximum length for flexible conduit.
Do you know the code cycle when the inspector made the comment?

There is no 6' limit for LFMC.

I recall years ago maybe 15 or so I heard the same exact thing about it. No one ever had a code article but many people said the same exact thing.

No book with me but I think that 3/8" may have a length limit?

I believe the 2011 NEC was the last addition that limited Liquidtight conduit to 6' for packaged SPA/Hot Tub units

6 foot limit if I remember is for vibration for no straping. I think there something that says 6’

2011 NEC Below:

Currently it’s 6’ without straps, and must comply with strapping if over 6’, which is every 4 1/2’.
