Do cables need UL certification?
A track cable needs to be UL approved. For this, two standard jacket compounds are available to choose from — PUR and PVC. PVC jackets can be CM or CMG listed.
What is dual rated wire?
A dual rated cable is a cable that lists two different voltage ratings on its jacket. For instance, a cable with 115 mils insulation thickness may have a jacket with a print legend that lists both 5kV and 8kV voltages at 133% and 100% insulation levels respectively on it.
What does VW 1 mean on wire?
VW-1: These cables have passed a VW-1 flame test and carry a “fire resistant” designation. The VW-1 test provides an assessment of the cable insulation material and resilience to fire. This is one of the most severe tests since it’s performed vertically and can be viewed as a worst-case test condition.
What is UL style?
