Here's one of many similar installations I recently saw at an outdoor shopping mall. The wiring methods used here do not meet the following Code rules.
As per part of 356.10, liquidtight flexible nonmetallic conduit (LFNC)shallbepermittedinexposed orconcealedlocations wherelistedandmarkedassuitableforthepurpose or for direct burial where listed and marked for the purpose.
LFNC shall not be used where subject to physical damage (356.12).
"Ferrous or nonferrous EMT, elbows, couplings, and fittings shall be permitted to be installed in concrete, indirect contact with the earth, or in areas subject to severe corrosive influences where protected by corrosion protection and approved as suitable for the condition." (358.10)
Enclosures within the scope of Art. 314 shall be supported in accordance with one or more of the provisions outlined in 314.23(A) through (H). More specifically, "An enclosure that contains a device(s), other than splicing devices, or supports a luminaire(s), lampholder, or other equipment and is supported by entering raceways shall not exceed 1,650 cm3 (100 in.3) in size. It shall have threaded entries or have hubs identified for the purpose. It shall be supported by two or more conduits threaded wrench tight into the enclosure or hubs. Each conduit shall be secured within 450 mm (18 in.) of the enclosure." [314.23(F)]
