Revised Text
225.10 Wiring on Buildings (or Other Structures).
The installation of outside wiring on surfaces of buildings (or other structures) shall be permitted for circuits of not over 1000 volts, nominal, as specified in Table 225.10. as open wiring on insulators, as multiconductor cable, as Type MC cable, as Type UF cable, as Type MI cable, as messenger-supported wiring, in rigid metal conduit (RMC), in intermediate metal conduit (IMC), in rigid polyvinyl chloride (PVC) conduit, in reinforced thermosetting resin conduit (RTRC), in cable trays, as cablebus, in wireways, in auxiliary gutters, in electrical metallic tubing (EMT), in flexible metal conduit (FMC), in liquidtight flexible metal conduit (LFMC), in liquidtight flexible nonmetallic conduit (LFNC), and in busways. Circuits of over 1000 volts, nominal, shall be installed as provided in 300.37 and Article 399.
Table 225.10 Wiring Methods not over 1000 volts.
open wiring on insulators
cable: multiconductor, ITC, MC, MI, SE, TC, UF
messenger-supported wiring
rigid conduit: IMC, PVC, RMC, RTRC
tubing: EMT
flexible conduit: FMT, LFMC, LFNC
auxiliary gutters, busways, cable trays, cablebus, wireways
Substantiation
The table format is much easier to read. Cable Types ITC, SE, TC are also suitable.
Since Article 399 is about outdoor conductors over 1000V it should be referenced as well.
