I hate butt slices as well. They'll work fine for a while but down the road you'll wish you had used terminal strips.
Yeah, if you use the wrong tools....
Well drillers use heat shrink butt splices every day of the year on fully submerged well pumps. There are millions upon millions of artesian wells in the US using fully submerged heat shrink butt splices.... These butt splices exceed 20-30 years fully submerged, some to depths of 300+ feet.. Our last well was 340 +/- feet and had heat shrink butt splices at the well pump. Most of the year water
naturally flowed out the well cap... The heat shrink butt splices we use on boats are really no different than what are used on well pumps..
I probably exceed 7000 terminations per year, yesterday alone was at least 80, and I have never once had a butt splice fail. Do I see failed butts? Yes, but they were ALL done incorrectly or were the wrong type/choice for the application. Done correctly, with the right tools & quality terminals, they will last as long as the wire..
People often incorrectly malign the butt splice because they simply don't know any better. Because it is an extruded copper tube the crimp and terminal itself are actually more robust/rugged than a brazed seam ring terminal. Why? Because a quality butt splice has no BRAZED SEAM to fail.
I have NEVER had a butt splice split but I have seen plenty of ring terminals split the brazed seam. Heck many elcheapo ring terminals are not even brazed, but most butt splices, even cheap
ones, are solid copper tube because it is actually less expensive to manufacture....
Ring Terminal = Stamp, roll form, braze seam, strain relief sleeve, tin plate
Butt Splice = cut copper extrusion, wire stop dimple, tin plate
Butt Splice = 2
Terminal Strip = 4
Both work fine if done correctly with the right tools but there is only ONE I would put in a moist area of a boat and that is not the t-strip and ring terminals...
Does the lowly butt splice deserve a bad rap because of knuckle heads who install open butts in a bilge
Does the lowly butt splice deserve a bad rap because of knuckle heads who don't even crimp the terminal and crimp only the insulation
It always seems to be the fault of the gun (butt splice) not the person pulling the trigger (crimp tool).
Someone has to defend the lowly butt splice....
