Whats the voltage rating on this wire?

lgreen · 20th October 2004, 06:00 PM

I want to use some of this wire but I'm not sure of its voltage rating, here is the spec sheet:

http://www.jscwire.com/jsc_ss.taf?p=6091

It says UL CM and CMH but I can't figure out what those mean.

I hope to use this for 117 V AC and 80V DC.

Hi
Just guessing but your cable looks very similar to trailer lighting cable used for 12v. The inner insulation is thin and may not be robust enough to avoid damage. If it is trailer cable its voltage rating maybe 50vdc. Remember 117vac is 165v peak and add in say 6% regulation comes to 175v.
Try emailing the supplier.

OK, I called their customer service and they said 300V. Seems a little high.

All sorts of wire is rated to astronomical values... frankly, I'd be scared if I saw 50V wire connected to a car battery. I mean, that's like no insulation on there. More of a mechanical than electrical hazard, it'll wear through easily.

I think most house wiring (10-14AWG) is rated around 600...
