Hi Ray,
I have for my last 2 battery jobs used the Cobra X-Flex in 2/0 size with MTW rating. At the battery end I have found the Thomas & Betts 54163-TB lugs, available at my local Grainger store to be a good match both mechanically and specification wise (also the correct hole size for M8 terminals in my Concorde AGM's). On the usual electrical equipment end, I use a Greaves Shoo-Pin PT131FX20 as the appropriate reducer to a THHN stranding #2/0 size (available through our local Graybar store, drop shipped to my office). Because I am using a Sunny Island, of course nothing #2 fits. so I have two Polaris style connectors in the trough below the SI where I switch from the Shoo-Pins to four #1 THHN to go up into the SI batt terminals (two conductors per pole). In fact, I am wrapping up one of these installs right now. Don't know if this helps, -Glenn -----Original Message----- From: re-wrenches-boun...@lists.re-wrenches.org [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of R Ray Walters Sent: Monday, November 29, 2010 11:58 AM To: RE-wrenches Subject: [RE-wrenches] Battery Cable REvistied HI All; I have struggled for years to get the right battery cable; in the old, old days we used welding cable, which was better than THHN, but not with the AHJs. Then we used a SAE battery cable with 532 strands that was ideal, but not UL listed. Next we used Cobra X flex, but at over 2000 strands, we had the problem it wasn't rated for some of the mechanical lugs and breakers. (too fine a stranding) Now I've found what I think is the perfect cable: Cobra Cop Flex, class I. http://cobrawire.com/copflex/class_i.php It's UL listed RHH, RHW , but is coarser stranded 532 strands, but not as coarse as standard THHN (19 strands). What do you guys think? RHH, RHW meets the code, with the coarser stranding not being a problem with regular lugs, but still way more flexible than THHN. We're saved right? R.
