Hook-up/building wire is used extensively for electrical connections in control panels. Type MTW is flexible and easy to handle; Type TFFN is primarily used as fixture wire; Type THHN is intended for general purpose applications. Type DLO is ideal for heavy duty wet/dry power connections requiring flex.
Hook-up (building) wire is the primary component for connecting electrical signals in industrial or commercial applications. While the NFPA allows the use of MTW or THHN wire inside control panels, MTW is often preferred for its flexibility and easier handling. Type TFFN (stranded) wire is primarily used as fixture wire as specified by the National Electrical Code (NEC). Type THHN wire is suitable for general purpose applications; Type DLO is ideal for heavy duty wet/dry power connections requiring flexing capability.

MTW wire is a PVC hookup wire, commonly used in control cabinets, that features a highly stranded conductor for more flexibility than other building wire and also provides increased protection from moisture and corrosion.
Thermoplastic Flexible Fixture Nylon (TFFN) wire, primarily used as fixture wire, is highly flexible and has a copper core with a slick nylon jacket for easy pulling.
Thermoplastic High Heat- Resistant Nylon (THHN) building wire offers a PVC insulated nylon sheath for easy pulling and is intended for general purpose applications as defined by the National Electrical Code (NEC). It is appropriate for new construction or rewiring for 600 volt applications.
DLO, RHH / RHW-2 heavy-duty flexible power cable is 2kV rated for a variety of applications including industrial control panel power distribution and power feeds for variable frequency drives, as well as non-traditional industrial applications like drilling rigs, railroad/transit car wiring, and mining equipment. This cable is available cut to your specified lengths in 1-foot increments (10 or 20 ft. minimum depending on style/wire size).
