Dual voltage rating
Dual voltage rating
(OP)
I would like to understand why the same cable has dual
voltage rating: UL/CSA/TC: 600V and UL AWM 1000V. I am
wondering now what is the actual voltage the insulation
is designed to withstand? (To be more specific, I mean
the OLFLEX part number 760204).

RE: Dual voltage rating
1000V is the limit for low voltage systems. Practically, the system low voltage within the power distribution system ends with 600V level (or Class). See IEEE Std 100 "Dictionary" or ANSI 84.1-1977 for Voltage Classes

TC 600V intended for cable tray installation of premises wiring per NEC Article 318. http://www.ul.com/regulators/mgwire.pdf
AWM 1000V ‘appliance wiring material’ — http://www.ul.com/wire/awm.html AWM wires are intended as factory installed or factory provided components of complete equipment submitted for investigation, rather than for direct separate installation in the field. http://ulstandardsinfonet.ul.com/scopes/... {One example is ballast-to-lamp wiring at 750V.}
