IEC320 Jumper Cables – Why does this cord say 17 AWG instead of 18 AWG?

Leave a comment

Recently UL, CSA, and ANCE have made changes to the flexible cord and cable standards shared by all three agencies. The change will affect the following standard: UL 62, CSA 22.2, and NMX-J_436-ANCE. The cables that will be affected by this change are dual or multi rated cables, like IEC Jumper Style cordsets. All of Webber Electronics‘ dual rated jumper cords are already in full compliance with this new standard.

We manufacture our IEC Jumper Cords with multinational listings for Universal use anywhere in the world. Prior to this change, international cable type HO5VV-F 3*1.00mm2, was considered equivalent to 18 AWG 3 conductor SJT cable. However, 3*1.00mm2 is technically a little larger than 18AWG. The new standard will require more accurate classification of these cables. Moving forward, an odd (larger) AWG will be assigned to these dual rated cordsets. In American Wire Gauge measurements, the larger the gauge or thickness of the wire, the smaller the number gets. Typically 18AWG is smallest for AC cables, because it reaches the minimum capacity for 10 AMPs and 125 volts, and 14AWG is usually where it maxes for that range of cables rated at 15 AMPs and 125 volts. Because of the size difference in metric vs. AWG, HO5VV-F 3*1.00mm2 will be listed as 17AWG instead of 18AWG. In fact, you will see odd AWG sizes appear like, 17, 15, 13, and 11. This is a more accurate classification, and will help our customers better identify their cable needs.
