AWM 2103, PVC Jacketed Multi-Conductor Appliance Wiring Material

UL AWM Style 2103 is the multi-conductor member of the family: two or more insulated conductors, 30 AWG to 10 AWG, twisted into pairs, gathered into groups, or laid parallel as a flat, oval or round cable, then closed with an extruded PVC jacket. Rating is 105°C and 300 Vac with horizontal flame. The jacket is where the style differs from a single conductor: wall thickness is set by the diameter under the jacket, from 15 mils minimum average on anything up to 8.9 mm, stepping to 30, 45 and 60 mils as the cable grows. Shield, barrier layer, fillers and covering are all optional, so the same style number covers an unshielded control lead and a shielded sensor cable. Use is internal wiring, which is the one thing to keep in mind: 2103 belongs inside the enclosure. For an external run that sees sun and oil, the same construction with a heavier jacket is AWM 21894.
