Reduced size conduit supporting a threaded junction box like a guat

[ARCTICSKI]

An 1 1/2" GUAT has 3 conduits threaded into it, smaller than the trade size of the GUAT. ie. a 1", and 2 @ 3/4" GRS CONDUITS, using reducers. Is this a 2008 NEC violation, even if all of the conduits are supported within 3 feet of this J-B??? :roll:

Pardon me for asking but what is a GUAT?

Also check out 314.23(E) for enclosures supported by raceways.

It is a threaded hub cast JB. It may be explosion proof.

OK Thanks, I had just never heard the term before.

314.23 (E) does not say that reducing bushings are not allowed! I do not see any violation there!

It is either a C-H or OZ part number.
