Looks like it is within a cabinet as covered by article 312 and specifically section 312.8.
I don't see anything wrong with it as long as the listing of that terminal strip does not require the conductors to wrap the screws.
Good up to 10awg as per 110.14(a)
Isn't that true of almost all terminal block?they are probably not listed, only recognized.
If the terminals block listed for used size I think you don't need barrel lug at end up to 10 awgSeems an extension of a single conductor to its termination(buss bar, breaker, lug) would be considered a splice -- If that is true them the ends should be covered equivalent to that of the conductors or with an identified insulating device. NEC is unclear on the definitions of splice & termination.
Can you terminate in a barrel lug and not be required to insulate?
In my opinion that is two terminations and not a splice.Seems an extension of a single conductor to its termination(buss bar, breaker, lug) would be considered a splice -- If that is true them the ends should be covered equivalent to that of the conductors or with an identified insulating device.

Those are terminations, not splices. 110.14(A) not 110.14(B)
Each conductor terminates on each screw.
Or would you say the screws on a receptacle are splices and require insulating?
What's the difference between a termination and a splice? Are there any cases where it matters?
The way that I see it, is that any time a conductor ends its factory continuity, that is a termination. And a splice is a special case of a termination, where a new conductor emerges.

So we really can't use them in the field? As I understand it, a recognized component can only be used as a part of a complete listed product. The following is from a UL document.I don't know of any terminal blocks that are listed. Most power distribution blocks seem to be recognized as terminals as well.
Because components are only intended for installation in end products whose safety is evaluated by UL separately, they may be incomplete in construction or restricted in performance capabilities. This factor precludes their safe installation by electricians or contractors in the field.
Just looking at terminal blocks on Automation Direct site they offer both recognized and listed ones.I don't know of any terminal blocks that are listed. Most power distribution blocks seem to be recognized as terminals as well.

Just looking at the images seems the listed ones have the terminals set in deeper barriers, some have more separation between poles. Also the covers are mentioned as optional for the recognized ones and the listed ones all say a cover is required. May be more to it but that is a casual observation.
