George Simmons Posted January 4, 2011 Share Posted January 4, 2011 Here's a topic I haven't seen argued, er... I mean discussed, here before:Butt Splices.How do y''all feel about them? Love 'em or hate 'em, and why? Good idea or bad idea? Safe or unsafe? Link to comment Share on other sites More sharing options...

Guest guest Posted January 4, 2011 Share Posted January 4, 2011 had thought I might use them with the wiring harnesses I created for my mini trees using s shared neutral...but had no need...came up with a better way using inline SPT ends. Link to comment Share on other sites More sharing options...
Tim Fischer Posted January 4, 2011 Share Posted January 4, 2011 I use a lot of them too. Mostly for "in field" repairs, but when I first deployed my arches, I got lazy and did all the wiring harnesses with them as well because it was much quicker than the solder/heat shrink route I normally prefer.It's rare that I have a joint based on one of these fail.-Tim Link to comment Share on other sites More sharing options...
scubado Posted January 4, 2011 Share Posted January 4, 2011 Ok, now that I'm on the same page on what a butt splice is, I personally wouldn't use them in a stressful situation such as; wet weather, install/uninstall and stretching causing them to come apart or corrode. Solder and heatshrink tubing would be much better solution. Link to comment Share on other sites More sharing options...
djr Posted January 5, 2011 Share Posted January 5, 2011 I used over 100 this season. Had one GFI pop one time during several days of rain. I stopped the show that evening went out and found there was one connection in a puddle. Moved the offending connection to a higher location reset the GFI restarted the show still in the rain and no more problems. Link to comment Share on other sites More sharing options...

Dale J Posted January 5, 2011 Share Posted January 5, 2011 i had one of my led strings quit working just to find a cut wire probably from the Staples last year this one i took down and solder and used shrink tube but generally the butt connectors would be much quicker and just as good Link to comment Share on other sites More sharing options...
Steven Posted January 5, 2011 Share Posted January 5, 2011 Invest in a good crimp tool (ratcheting). You'll only need to buy it once and it will make the crimps consistent.When crimping light string wire (thin gauge) strip it long, then fold it back on itself once or twice and twist it to give the splice something to bite.I inject silicon caulk into the butt splices before I crimp them. I'm not sure if that helps or not, so I'd appreciate any feedback. Link to comment Share on other sites More sharing options...

Otherwise you'd buy it more than once Second point - very good adviceThird point - I'd inject it after doing the crimp, so it wouldn't accidentally insulate something you're trying to do a good connection on.

Found out the hard way the white or dark stuff works fine another is the red RTV. That we used at work before I retired can't find it anymore .

Dennis Eaton Posted January 5, 2011 Share Posted January 5, 2011 Plastic tip as you call it (rupperized paint) works well only issue not a quick fix in the feild takes a bit to dry but looks good and you can match colors. I found that it will take about 3 dips to give a thick coat. All the feild repairs I ahve made have been with the heat shrink splices the one major down side is being carefull not to smoke your wire while heating the heat shrink found that one out the hard way...

friskybri Posted January 5, 2011 Share Posted January 5, 2011 I use them in all the arches and light poles. I also use them in field repair of icicle lights because its a pain to get 4 layers of them out over a 14 foot section. So if I cant find the problem with the lights I cut out the section and put in another and splice. I don't use the shrink ones, its a waist for the cost. You can get like 100 for 2 to 3 dollars online. I can take hot clue and glue the ends and that not only keeps the water out but keeps it from being pulled out.I get mine from here.http://www.mpja.com/prodinfo.asp?number=0222+TM Link to comment Share on other sites More sharing options...

When heating the tube from the middle it will push the liquid out and seal each end. Link to comment Share on other sites More sharing options...

It worked great, even in the rain. I was careful to be sure that I crimped the wire and then the insulation too so the joint was a bit stronger than wire alone.

Dr. Jones Posted January 6, 2011 Share Posted January 6, 2011 I use butt splices almost daily for work. For our work we use both the insullated type and the non-insulated types. For ease of use the insulated ones work great ( we generally use the heatshrink/adhesive type). For the larger wire 14-1ga The non-insulated work the best, as the shrink that come in the kits contains more adhesive and seals to the wire better.as for crimpers - I use both ratchetting type and the non-ratchetting type- I still prefer my Klien non-ratchetting crimpersalso- a word of advice- know what type of butt splice you are using( as I do a lot of work hot, I have witnessed people using the non-insulated crimper on an insullated splice and they were in for a shocking experience) Link to comment Share on other sites More sharing options...
kzaas Posted January 6, 2011 Share Posted January 6, 2011 I too use butt splices, but I have a question for you guys. Why are you worried about sealing the splice when your plugs aren't sealed and neither are the lights? Link to comment Share on other sites More sharing options...
