THHN/THWN building wires are used for general-purpose applications such as supplying power and lighting in residential and commercial buildings. These cables can be installed in ducts, conduits, and raceways, and in wet and dry locations. The applications for different wire types are classified as follows:

• THHN 105°C for dry locations, building wire
• THWN 75°C for wet locations, building wire
• TFFN 105°C for dry locations, flexible cord and fixture wire

Single-core AWM building wires are used for internal wiring of appliances, including wiring for refrigeration equipment, air-conditioning equipment, automatic washers, etc. Type AWM is permitted for use in 600 V applications and for dry locations at temperatures not exceeding 105°C.

• Plain annealed stranded copper conductor
• Color coded polyvinyl chloride (PVC), heat, moisture and flame retardant compound with a temperature rating of 105°C.
• Wires meet UL (VW-1) flame test requirements

Suitable for domestic and light industrial wiring and can be installed on tray, free air or clipped direct. It should be installed into areas where there is low risk of mechanical damage. Also used for transferring electrical signals among different control units and also used in alarm systems.

• H05VV-U cables are designed and tested to meet or exceed the requirements of IEC 60227-4 standard
• Plain annealed solid copper conductor class 1 as per IEC 6022
• H05VV-R cables have been tested and approved with the flame performance standards IEC 60332-1-2
