Systems of Insulating Materials — UL Standard 1446.
This is a guide intended for UL approved insulation systems connected to branch circuits of 600V or less.
Approval required by Underwriters Laboratories when using lead wire with a temperature rating more than 5°C under the system temperature rating.

Switches Rope Lay)* Rope Lay)* Rope Lay)* Rope Lay)* Rope Lay)*
Note: For a given AWG wire size (based on equal cross-sectional area of conductor), limpness and flex life are increased by use of a large number of fine strands. The finer stranding does result in higher costs.
*Rope Lay is several stranded groups cabled together. For example: 12 AWG, 259 x 36 is 7 cords each consisting of 37 strands of 36 AWG.
