Several brands of power cable list their rating at a dual 600/1000v. it is my understanding that to be listed in this manner, the cable must pass a test apply of over 600v for a short period without breakdown. But under normal operation IMO, the voltage is not to exceed 600v. And this test is done with AC voltage, not DC.<div><span style="font-size:12pt;color:rgb(51,51,51);font-family:oswald,sans-serif"><br></span></div><div><span style="font-size:12pt;color:rgb(51,51,51);font-family:oswald,sans-serif">"<b>UL 1277: Power and Control Tray Cable</b></span><br></div><div><p style="box-sizing:border-box;margin-bottom:8px;margin-top:0px;padding-top:0px;padding-bottom:0px;color:rgb(51,51,51);font-family:lato,sans-serif;line-height:22px">UL 1277, the standard for electrical power and control tray cable, was recently updated, allowing manufacturers with UL approved tray cable to market their product as 600V/1kV rated. To be dual rated, products must use a recognized 1kV rated conductor and pass a higher voltage AC Hipot test on the completed cable. This test requires each insulated conductor in finished cable to withstand a specified voltage range for one minute without breakdown. If a product passes the AC Hipot test, it is suitable for 1kV use."</p><div></div><div><br></div><div>Am I getting this right? And If so, one should not use this 600/1000v wire if normal operating voltage is above 600v as is my case? Proper rating should be dual 1000/2000v like PV wire?</div><div><br></div><div>What do you experienced high voltage battery gurus use in my application? Thanks.</div></div></div>_______________________________________________<br>
