It addresses Type UF cable. The designation "UF" stands for
Underground Feeder but you can also use this cable for branch circuits [340.1].
The cable has a nonmetallic sheath and is suitable for direct burial [340.2].
Article
340 lists seven uses. Obviously, it can be used underground. But there are half
a dozen other uses, including solar voltaic systems and for wiring in wet or
corrosive locations [340.10]. -
As with
most wiring methods, you can't
use it where it's exposed to physical damage. With any wiring method, you should
assume that restriction unless the Code says otherwise.
Methods such as rigid conduit and intermediate conduit (Articles 342 and 342,
respectively) fill this particular niche, but even in those cases you want to
reduce the exposure as much as is practical. Article 340 lists ten other
prohibited uses, and most of those are specific types of occupancies (e.g.,
movie theaters) [340.12].

You can use any hardware
suitable to the application and to the size cable you are using. Whatever you
do, don't exceed the bend radius [340.24].

Article 340
doesn't specify the types of terminations to be used. You can use any types of
terminations suitable to the application and to the size cable you are using.
