Re: [RE-wrenches] Wire nuts

Rooftop/Combiner splicing is a perfect application for the use of splice capped crimp sleeves. The other is where splices are subject to vibration. Their usage seems to vary throughout the country. In NW Oregon, where I came up in the trade, it was protocol to use them in places like rooftop

Mike: Without doing a lot of research, I seem to recall what you are stating about using the Buchanan splices is true if the PV wire, micro-inverter trunk cable, or DC optimizer fine stranded wire is 19 strands or less. Regards, Gary Willett Icarus Engineering LLC Sent from my iPhone 5s >

Never had an issue, they crimp fine. But just like with any electrical work, you must pay attention all day long! Mike On Tue, Sep 6, 2016 at 4:21 PM, Benn Kilburn wrote: > August, et al, > Do you have any issues with crimping the fine wires that are typically on > a

Re: [RE-wrenches] RE-wrenches, Wire Nuts

Wrenches, I would like to concur with Mike from MDElectricSolar. My rooftop junctions always use Buchanan copper sleeves crimped with the Buchanan C-24 crimp pliers. After twisting the stripped ends together to a length exceeding the sleeve length I apply No-Ox-ID A Special grease to the

Re: [RE-wrenches] Wire nuts

We’re using ideal/Buchanan splice cap crimp connectors as I’ve posted here a couple of times: http://www.idealind.com/ideal-electrical/us/en/products/wire-termination/60-crimp-connectors/copper-splice-cap-crimp-connectors.aspx We really like these in nearly every way. I just spoke with Ideal

Re: [RE-wrenches] Wire nuts

Again, I am using Buchannon copper crimp sleeves, with a Buchannon crimper, never seen one NOT work or go BAD. This is the best connection I have seen. I've never had an inspector open up my rooftop j-box/combiner box and ask about the listing of my connectors, but as a solar business owner who's

Re: [RE-wrenches] Wire nuts

The reason i'm asking is that the only time i have seen a short, first-hand, in a wire nut, was because it appeared that one wire was pushed down rather than binding with the other wire, which would have happened if the wires were not held tightly when the nut was twisted on. Also, it was a

All the other nuts are tight so l cant not say it was or not but l see this alot and this was one that was caught just at the right time. Jerry On Sep 6, 2016 8:44 AM, "Benn Kilburn" wrote: > Jerry, > Can you confirm that this was caused by a failure of the wire nut,

Re: [RE-wrenches] Wire nuts

Jerry, Can you confirm that this was caused by a failure of the wire nut, itself, and not due to user error (not properly stripping enough jacket, inserting even length wires and sufficiently twisting on the wire nut) Benn Kilburn SkyFire Energy Inc. 780-906-7807 > On Sep 6, 2016, at 12:32

Re: [RE-wrenches] Test procedure for Concorde batteries

Hi Larry John Pfeifer at Apollo Solar sponsored the testing and now John has disappeared from the solar scene altogether. I don’t have any contact info for him. BTW the Concordes have been working without a hitch for eight years now. Kind regards Tom Duffy Senior Solar Design Engineer

Re: [RE-wrenches] Test procedure for Concorde batteries

Larry It looks like the UPG batteries come from the same Chinese factory as well. We’re hoping the Trojan Reliant work out well with their re-introduction Q1 2017. AGM batteries seem to be the most misunderstood (after Gels) I have noticed the failure rate is higher than wet, I assume most
